John: Marshmallows...Lucky Charms man. Trust me, I was a non-believer at first too but you'll come around. The Cheese-Marshmallow Theory can not be disproved!

Homestar: "Before I drink a tall glass of melonade, I like to eat about 147 FLUSHY PUSH MARSHMELLOWS! Seriously folks..."
Director: "Cut! You said Flushy Push."
Homestar: "I know! Can you believe it?!?!"
Director: "They're called Fluffy Puff."
Homestar: "I know! Can you believe it?!?!"
"Before I drink something, often times I eat something too!"
"Before I drink a tall slice or marmalade I eat 147 marshmellows. I mean fluffy puffies."
"They're fluffity! They're puffity! 12345!"
