"Mom! Dad! I just had the most incredible dream. I dreamt I was in Imaginationland"

"You were in Imaginationland, Butters. We read all about it in the papers. What were you doing there? You were supposed to be helping your mother in the basement!"

"You're grounded, Mister!"

"Awww.... wait.. no I'm not grounded" *tries to imagine himself getting out of trouble*

"Son, that only works in Imaginationland. You're grounded!"

"Awww shit."

Butters is the man.
