Rufio: Hemorrhoidal suck naval.
Peter: Or maybe a fifth grade reading level.
Rufio: Boil dripping beef fart sniffing bubble butt.
Peter: Someone has a severe ca-ca mouth, you know that?

Peter: Substitute chemistry teacher!
Rufio: Mung tongue!

Rufio: Pinhead!
Peter: Prison barber!
Rufio: Mother lover!
Peter: Nearsighted gynecologist!!
Rufio: In your face, camel cake!

Rufio: Lying, crying, spying, prying ultra-pig!!
Peter: You lewd, crude, rude, bag of pre-chewed food dude!!
Rufio: You... you man! You stupid, stupid man!
Peter: Rufio, if I'm a maggot burger why don't you EAT ME, you two-toned zebra-headed paramecium brain, munchin' on your own mucus, suffering from Peter Pan envy?!
Kid/Bystander : ... What's a paramecium brain?
Peter Banning: I'll tell you what a paramecium is. It's a one-celled critter with no brain, that can't fly!! Don't mess with me man, I'm a lawyer!
