Chris Pratt Can't Stop Laughing While Playing His Mom's Favorite Game With Ellen

"I'm gonna bump you."

We never tire of watching Chris Pratt play silly games, whether he's making up insults for Jennifer Lawrence or prank calling a pet store in alphabetical order. His latest game of Speak Out with Ellen DeGeneres was no exception, and it even came with a special Mother's Day connection.

Pratt says Speak Out is one his mom's favorite games, and it doesn't take long to see why. If you're not familiar with the game, it involves one player holding their mouth open with a mouthpiece while the other tries to guess what they're saying.

Things go pretty smoothly for Pratt and the host, with sentences about parakeets and free doughnuts. But when they get to the sentence "I'm gonna bump you," things get giggly. Pratt realizes how inappropriate it sounded, and he can't seem to stop laughing.

"That really did sound bad," he admits, before trying a few more times. It sounds just as bad every time he says it, which only leads to more laughter. DeGeneres even has to grab a tissue to wipe the tears from her eyes.

Eventually, Pratt resorts to singing the Black Eyed Peas' "My Humps," which seems counterintuitive. The host finally ends up figuring it out when Pratt fist bumps himself. Sometimes you just have to get creative.
