The first rule of Fight Club Toy Story [1] is: you cannot talk in your character's voice outside of the filming environment . . . and Tim Allen learned that the hard way! The actor recently sat down on The Kelly Clarkson Show [2] where he told Kelly about a jarring incident that essentially forced him to use his Buzz Lightyear voice [3]. He explained that he was in an elevator when he witnessed a young kid misbehaving and being rude to his mother, so he decided to unleash the wise words of Buzz [4] onto this child.

"I said, 'To infinity and beyond, you shouldn't treat your mom like that,'" Tim shared. The kid was immediately shell-shocked and started crying, telling his mom, "That ugly man swallowed Buzz Lightyear!" Watch the video above and hear Tim's story about a time he and Tom Hanks (aka Woody) [5] surprised patients at a children's hospital with their characters' voices.
