The NBC comedy "Undateable" returns Oct. 9 at 8 p.m. with a twist -- every episode will air live on the East Coast. Here are five other sitcoms that have aired without a net:

GIMME A BREAK! (Feb. 23, 1985) -- In "Cat Story," Nell (Nell Carter) and others are worried about what happened to Officer Simpson (Howard Morton). He disappeared during a torrential rainstorm while trying to save a cat and is presumed to have died.

ROC (1992-93) -- Every episode of the second season of the Fox comedy starring Charles S. Dutton aired live. Many of the cast had Broadway experience, which came in handy.

THE DREW CAREY SHOW (Nov. 10, 1999; Nov. 8, 2000; Nov. 14, 2001) -- The ABC comedy went live three times; the 2001 episode featured a lot of improvisation from Carey's colleagues at his game show, "Whose Line Is It Anyway?"

WILL & GRACE (Sept. 29, 2005, and Jan. 12, 2006) -- The second live episode, "Bathroom Humor," was particularly suited for live TV. It featured the show's four principal characters locked in a bathroom together.

30 ROCK (Oct. 14, 2010, and April 25, 2012) -- The latter is considered one of the show's funniest episodes: Featuring guest appearances from Kim Kardashian, Paul McCartney, Jon Hamm and Jimmy Fallon (to name just a few), it concerned the decision by Jack Donaghy (Alec Baldwin) to cease live broadcasts of "TGS" in order to fatten GE's bottom line.
