Professor X [sitting in his wheel chair] 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 thats cool and all, but not really a super power…”
r>Girl: “Yeah I was jut kidding, I can heal paraplegics”

Professor X, still standing: “Oh my god”
