The possibilities are endless, but I chose some of those lines because they seem so damn fitting for an action figure to say.
Here are some of my other ideas:
Hobo in brown shirt: "I don't care what you think of me!"
"Shut your mouth you prissy jerk!"
Peanut: "Walkin' tall!"
Vance: "What's the deal, pinwheel?"
Russell: "Russell SMASH!"
Const.: "Life sucks and then you die"
Ray: "I can't believe my mom won't let me eat sugar....'cause this feels awesome!"
