Featured sketches and recurring characters

-Tairy Greene: Played by Zach Galifianakis, a multi-talented actor known for his work in a Gravy Robbers restaurant employee training video, and the hit action television show "The Snuggler", where he played a man who helped people by snuggling them. As The Snuggler, he rescued Tim from the woods after an attack by Chippy's mother by nursing him back to health with snuggles and rehabilitation. He also hosted the "Tairy Greene Acting Seminar For Children" in which he did not teach the children to become different people through holding the nose, and never wants this said to him.

-Uncle Muscles Hour: Casey Tatum and his Brother (portrayed by Heidecker and Wareheim) perform various live songs lampooning telethon musical acts. The skit is carried over from a series of promos for Tim and Eric's previous collaborative effort Tom Goes to the Mayor. Casey is portrayed as having a very bad case of eczema and is usually uncomfortable, easily overcome with extreme, debilitating stage fright, and often on the threshold of either crying or vomiting. Casey died in the second season in a fiery car crash at the age of 17, however, he re-appeared in the next season. The titular host of the show is played by Weird Al Yankovic.

Chippy: Chippy, an animated character (as opposed to live-action which the other examples are), is a wild creature, often seen in very brief bits (usually as a link) in which he is found hiding in a background. The Chippy resembles a hirsute baby, with a handlebar mustache and an abnormally large unibrow. The Chippy is always in distress and any scene with the Chippy almost always ends with it emitting a high-pitched screech. In the episode "Forest", the Chippy's mother (played by Eric) viciously attacks Tim while on a nature hike.

Richard Dunn: A senior citizen who has become a part of nearly every episode since the middle of season 1.

David Liebe Hart: A singer and puppeteer who performs listless songs with an assortment of ventriloquist dummies. His songs usually have positive, upbeat themes. He almost always has a Bluetooth headset in his right ear, and is often accompanied by psychedelic green screen effects.

Beaver Boys: A pair of party boys (portrayed by Heidecker and Wareheim) who often prowl the beach for women. They are seen as having a penchant for cocktail shrimp and white wine, which is further emphasized in the lyrics to their show's accompanying theme song.

Spagett: A hyperactive overweight middle-aged man with a black ponytail, visible hair plugs, and dried spaghetti sauce around his lips who hides behind various objects and "spooks" people on his hidden camera television show by yelling out his name. His hiding places are always in plain view and as a result, his victims are never taken by surprise; instead referring to the incidents as awkward or abnormal. Later becomes the mascot for "Cigarette Juice" Spagett is played by Tim Heidecker.

Channel 5 Married News Team: Jan and Wayne Skylar (portrayed by Heidecker and Wareheim) are television news anchors who are married (to each other), and less than modest about displaying their affection for each other on air. These characters were also carried over from the duo's previous Adult Swim show, Tom Goes to the Mayor.

Brule's Rules with Dr Steve Brule: An inept news reporter (played by John C. Reilly) who often appears uncomfortable being on air. He is featured in a number of the sketches alongside the Channel 5 Married News Team. This segment lampoons the do-it-yourself segments featured on many local news stations. His catchphrase is "For Your Health!" which is said at the end of his segments.

Cinco: Carried over from Tom Goes to the Mayor, the Cinco Family/Corporation parodies the typical "soul-less corporations." Their cache consists of satirical products marketed with the name "Cinco Chemicals and Toy Division." Companies owned by the Cinco Family include Cinco Dairy, Cinco Sweets, Cinco Home Entertainment, Cinco Banking, Cinco Insurance, Cinco Styles, Cinco Chemicals and Toy Division, and other canon and non-canon subsidiaries. The commercials and infomercials use green screen and special effects with the intent of mimicking the standard format of infomercials from the late 1980s and early 1990s, often lampooning technology from the same era (such as the Cinco MIDI Organizer). Generally, the goods and services sold by Cinco companies are an assortment of seemingly useless products. The product names are often a simple contraction of two words, resulting in very unappealing names such as T'ird (A feathered flying disc with the legs of a turtle), B'ougar (a stuffed bear with the growl of a cougar), and B'owl (a stuffed animal meant to resemble a combination of a bat and an owl). See List of Cinco Family Products.

Channel 5 Kid Break: A series of pseudo-educational musical segments in which two "children" (Heidecker and Wareheim) rap about personal hygiene and family situations.

James Quall: An actor/comedian known for his unintentionally bad impressions of such celebrities as Jack Nicholson and Michael Jackson. His claim to fame is being a man of 12+ voices. His impressions almost always include him saying, "Spaghetti and Meatballs!" A fictional movie based on the life of James Quall (with David Liebe Hart) had Bill Hader portraying him.

Pierre: Is a father-obsessed singer and dancer (played by Ron Austar) who appears in various instructional videos teaching children how to dance to hip-hop and meditate while expressing his desire to meet their dads. In episode 18, while hosting the "Channel 5 Dance Party," Pierre reveals that he once impregnated Casey's mother.

Glen Tennis: An actor/director portrayed by A.D. Miles, Glen is the director of 'Crystal Shyps', which starred him and Ron Stark. The film appeared to have a very low budget. Later in Season One, Glen Tennis was invited to talk to Danny Mothers (Bob Odenkirk) about his film on 'Channel 5 Looking at Films'. In Season Two Glen tried to sell some Crystal Shyps memorabilia in an infomercial. He was interrupted by his brother David, who called in to 'harmlessly rib' him. Glen ended up getting very upset and destroying all of his merchandise. Glen Tennis has a terrible temper and won't stand for 'crappy acting', as seen in extra material included with the Season One DVD.

Carol and Mr. Henderson: Carol and Mr. Henderson work together in a typical office setting. (Played by Wareheim and Heidecker) Mr. Henderson, Carol's boss, is a balding man with glasses. Carol is an obese lady who has a sexual obsession with Mr. Henderson. Mr. Henderson often stops by Carol's cubicle to sexually harass/tease her, saying things like, 'You look good enough for a poke.' This always excites Carol, and just when she is most excited, Mr. Henderson throws his coffee in her face. However, Mr. Henderson secretly adores Carol, but won't show it.

Afternoon Review: A daytime show "for women" in which strange men do surreal, odd, and slightly disturbing musical material such as a distorted guitar player, a mime who makes inhuman noises, convulsing men, belly dancing, sub-conscious memory exploration through odd noises, incomprehensible opera singing, drum solos by an old man, and dazed chanting. All of these bizarre performances take place in a room with a single stage, decorated with blue curtains with stars and balloons placed throughout it.

Grum: At first appearing in season 1, Grum is a badly rendered animated character who sings songs about how he likes 'crackers and snacks'. He appeared for the second time in season 4 with Glen Tennis in which they discuss their new animated (also badly rendered) movie "PilGrums". Grum is voiced by Tom Kenny.
