Kevin James wanted Here Comes the Boom to be so perfect for people of all ages that he wouldn't even let certain words be in the film.
"I used the word hate in a line when I ad-libbed," admits Henry Winkler. "And Kevin came over and said I don't want the word hate in this movie." A great way to make a fun, family-friendly film!
