Thomas "Tom" Baker (born October 27, 1953) is the father of twelve children and husband to Kate Baker. Tom grew up in a large family.
He wished that his own family would be large as well. He was a college footballer, beginning his relationship with Kate in his school years, and later developed ambitions to become a professional football coach. He and Kate had 12 children together and live, with their children, in Midland, Illinois, but later move to Evanston after Tom gets a chance to coach his former team, his dream job.
When he goes to Lake Winnetka with his family for the last time in Cheaper by the Dozen 2, he runs into Jimmy Murtaugh, a childhood friend, and the rivalry between them soon becomes evident. He ruins his daughter Sarah's first hang out with a boy and he starts to annoy his children by being dead set on winning the Labor Day Cup. When his oldest daughter Nora goes into labor, he's the one who waits outside while Kate, Bud and Lorraine go into the delivery room. Later, he resolves things with his family and gives his approval to his son Charlie regarding the plans he has for his future.
Tom Baker is played by Steve Martin in both films.
Tom Baker is also the Insolent Waiter from Jim Henson's The Muppet Movie when Kermit the Frog and Miss Piggy went out for dinner. In that scene from The Muppet Movie Tom Baker had a sip of the wine and spit and then said "excellent choice" in a beautiful voice that sounds like Bing Crosby's voice.
