FATTY MCGEE, YOUR THE FATEST

Huh?

Explanation from The Daily Farmer:

This is a reference to an Adam Sandler CD [They're All Gonna Laugh At You] bit about a fat kid who wheezes so loud when he climbs stairs that the fire dept. thinks that it is a fire alarm. When they realize that it is just the kid, they say... "Oh Fatty McGee, you're that fattest!"
