James Christopher Gaffigan (born July 7, 1966) is an American stand-up comic and an actor. His comedy routines are known for being deadpan, and often include humorous, high-pitched voices, such as that of a supposed audience member commenting on his performance. His performances are also known to commonly include his "dumb-idea guy" gags, during which he does a stereotypical redneck voice, declaring "Hey, I got an idea. How about...?", and going on to expand on the idea. For example, when talking about Hot Pockets, "Hey, I got an idea. How about we fill a pop tart with nasty meat." Gaffigan is also known for various routines relating to being lazy and eating food, especially famous bits regarding Hot Pockets and bacon.

Gaffigan was born in Chesterton, Indiana. He is married and a practicing Catholic.
