Chubby Bunny seems simple enough, but Jimmy Fallon learned the harsh reality with Rebel Wilson Friday on The Tonight Show.

All you have to do is stuff as many marshmallows in your mouth as you can while still being able to say the phrase “Chubby Bunny.” Wilson said she played this game on the set of How to Be Single, and now it seems Fallon has a new game for his guests.

While Wilson could barely say the phrase with three marshmallows, Fallon was pushing four as he fought back a giggle fit.
