James Christopher Gaffigan (born July 7, 1966) is an American stand-up comedian, actor, writer, and producer. His material often addresses fatherhood, laziness, food, religion, and general observations. He is regarded as a "clean" comic, using little profanity in his routines, although he does use it from time to time. He has released several successful comedy specials, including Mr. Universe, Obsessed, Cinco, and Quality Time, all of which have received Grammy nominations.
Gaffigan's memoir Dad Is Fat (2013) and his most recent book Food: A Love Story (2014) were both published by Crown Publishers. He co-created and starred in the TV Land series The Jim Gaffigan Show, based on his life. He collaborates extensively with his wife, actress Jeannie Gaffigan, with whom he has five children.
On Saturday Night Live, he appeared several times to impersonate Vice-presidential nominee/Minnesota Governor Tim Walz through the first few episodes of the show's 50th season.
