This off-the-wall assortment of bogus TV commercials, fake phone calls and inappropriate comic sketches features Tim Heidecker and Eric Wareheim, the creators of "Tom Goes to the Mayor." The show features appearances by a variety of celebrities -- a list that includes David Cross, John Mayer, John C. Reilly and "Weird Al" Yankovic.

Hailing from Rockefeller Center in the heart of New York City, Jimmy has made it his mission to make sure viewers end the day with a smile. Each weeknight, he hosts A-list guests, from movie stars to athletes, comedians, public figures and everyone in between. He also delivers a signature nightly monologue, performs in topical comedy sketches, plays fan-favorite games, and presents recurring segments like Thank You Notes. Today's popular musical guests also stop by to perform alongside house band The Roots.

From the minds of Adult Swim veterans Tim Heidecker and Eric Wareheim, this anthology's tales might best be described as horrifying, insane or -- at least -- dark. The 15-minute episodes feature various guest stars. While its gallows humor is distinctly Tim and Eric, the presentation quality probably won't jibe with what their fans are used to; the guys' longest-running show, "Tim and Eric's Awesome Show, Great Job," had a low-quality, public-access feel to it, whereas "Bedtime Stories" has high production values.

Oscar-nominated actor John C. Reilly ("Chicago") portrays naive and socially awkward Dr. Steve Brule in this Adult Swim series that sees the doctor examining various parts of everyday life. As he discusses such ordinary topics as boats, animals and money, Brule reveals information about his personal life, some of which is shocking and disturbing. Brule is joined throughout the series by recurring characters, who offer the likes of movie reviews and news updates.

Improv actor and comic Stephen Colbert flexes the hosting muscles he honed over nearly 1,500 episodes of the popular and critically celebrated "The Colbert Report" at the helm of this long-running late-night talk show. Following the genre's classic formula, each show kicks off with a monologue and a look at recent headlines, and features sketch comedy, celebrity interviews and musical performances. Joining Colbert is his bandleader, Julliard-trained Jon Batiste, and house band Stay Human. The show is filmed in New York's famed Ed Sullivan Theater, the longtime home of "The Late Show."

Heeeere's Conan! The former longtime host of "Late Night" and abbreviated presenter of "The Tonight Show" moves his talk show act to the cable arena, where he becomes the staple of TBS' late-night talk show lineup. Making the transition to basic cable with Conan is his on-again, off-again sidekick/announcer, Andy Richter. Said O'Brien in his typical dry tone, "In three months I've gone from network television to Twitter to performing live in theaters, and now I'm headed to basic cable. My plan is working perfectly."

Broadway, television and film star James Corden takes over the reins of the late-late-night franchise at CBS from fellow U.K. import Craig Ferguson. The British performer -- whose previous hosting gigs include five years of The Brit Awards -- puts his charm, warmth and creative instincts to use as he interviews celebrities and newsmakers, and hosts musical performances in his post-"Late Show" time slot.
