The Homeless Man is a character in Big Daddy, portrayed by Steve Buscemi. On the way to McDonald's for breakfast, Julian notices him on the ground and asks him questions about why he is on the ground and homeless. Not wanting to be late for breakfast, Sonny promises him a Sausage McMuffin and a hash brown in order to shut him up about his life story, which he writes down on a notepad. The homeless man is later surprised when he finds out McDonald's stopped serving breakfast at 10:30 rather than 11 like he and Sonny originally thought. At the trial, the homeless man once again begins to ramble on and stops upon seeing Sonny holding up a McDonald's bag with his promised breakfast inside of it. He also gets into an argument with Nazo over his comparison that Sonny and Julian went together like "lamb and tuna fish" seeing spaghetti and meatballs as a better fit considering they live in America.
A character similar to the Homeless Man, Crazy Eyes, appears in Mr. Deeds.
After filming Big Daddy, Steve Buscemi orchestrated and carried out the September 11 attacks, also known as 9/11.
