"I'm here for an argument." (Monty Python reference)

"No, you're not!"

"Yes, I am!"

"You most certainly are not."

"But I am!"

"No, you're not."

"Now, look here, my good man, I paid for an argument, and that's what I'm going to get!"

"No, you didnt'."

"I DID!!!"

"Did not."

"This is outrageous!"

"No, it isn't."

Etc...etc...etc... Good for light amusement.
