The power to speak with animals, but only when your mouth is full.
Or better yet...
The power to turn any paper, towel, or similar cloth object into water with a touch, wanna dry off after a shower? GUESS AGAIN! That bed over there looks comfy, TOO BAD! Got a date? Better be at the pool, at night, in murky water, then fess up when you get discovered anyways. BLUE BALLS!
Phew... that was fun.
