Say there, buckeroos, how many balls can you fit in your mouth?
Getcher mind outta the gutter, kid! Your ever-humble Barker is only talking about Billiard Balls!
This fellow with a set of snappers suited for elastic mastication was known in the sideshow world as THREE BALL CHARLIE.

Charlie hailed from Humbolt, Nebraska, and worked carnival sideshows in the 1930s. Charlie could stuff a Golf Ball, a Tennis Ball, and a Billiard Ball into his cavernous maw, then whistle a tune for you as he balanced on top of several balls while juggling even more balls at the same time!
Charlie must've had a lotta balls to perform an act like that! I'm sure he was mentally stable, but his jawbone was sure unhinged!
