The Cleveland Show Wiki

Zacharius Knight "Zach" Galifianakis (born October 1, 1969) is an American comedian and actor, known for his numerous film and television appearances including his own Comedy Central Presents special. While initially more of an "underground" comedian, he garnered mainstream attention with his role in the successful 2009 comedy film The Hangover.

Zack appears in "Cleveland Live!" when Roberta tells Cleveland that the chance of her staying with her father Robert Tubbs is just as likely as her staying with Zach Galifianakis.

At Comic-con in "Hot Cocoa Bang Bang", Harry Knowles faces off with Kevin Smith for a corn dog. When they collide, they merge into a huge blog that eats the conventioneers while imploring Zach to join them so they could be unstoppable.

Zach is voiced by Mike Henry.
