Cheese is great and random.
I LIKE CHOCOLATE MILK!
I enjoy all his appearances expect "maybe" Cheese-a-go-go...but maybe because that was quite a dull "out of Fosters" eps like "The Buck swaps here" and the "GOTTA GO"ing can be kinda irritating. He is also never overused, which I like. He is used in just the right does, which makes him funny everytime, instead of an "Ohno, not Cheese AGAIN *cringes*" feel.
I am also well aware that some people watch Fosters JUST FOR CHEESE! That it just....wierd.
