Girl
Professor X asks a girl, "what is your mutant power?"
Girl replies: "I can guess how many pulls to turn a ceiling fan off on the first try!"
She points up and says: "3 pulls"
Professor X stands up and pulls 3 times. After the third pull the fan turns off.
Professor X: "Yeah that's cool and all, but not really a super power..."
Girl: "Yeah I was jut kidding, I can heal paraplegics"
Professor X, still standing: "OH. MY. GODDD !!!!"
