Chubby bunny

From OAPedia.com

Chubby bunny is a game where you stuff marshmallows in your mouth, and utter the phrase "chubby bunny" after each one, until your mouth is so full that you can't say the phrase properly. The goal is to be able to fit the most marshmallows in your mouth while still being able to say the phrase. Opie and Anthony tried this game with various show staff members. E-Rock is one of the more memorable attempts.
