Ok, i gotta couple from one of my fav episodes...
"Pfft.. Clown College? ... You can't eat that.."
"These Krusty brand baloons are $3 each, get a cheap one and what happens? It goes off, takes out the eyeballs of every kid in the room! What's that gonna cost ya? .. Hey Bill, what did that cost us?"
"When i started this clown thing, i thought it would be nothing but glory.. you know, glory of being a clown.. But i tell ya, it's hard, tiring work. But when i see the smile on their little faces, i just know they're getting ready to jab me with something."
"Who am i clowning? I have no business being a clown. I'm leaving the clowning business to all the other clowns in the clowning business."
