Just imagine this action sequence...
An evil doer corners Levitation Man in an abandoned warehouse, then throws a handful of thumbtacks onto the ground. Levitation Man quickly uses his power of levitation to rise off the ground 3 inches above the tacks...but the clock is ticking down. He can only levitate for a total of 8 minutes. Cue the dramatic music. Cut to a close up of Levitation Man's face as a bead of sweat trickles past his impeccably groomed sideburns.
I'd pay to see what happens, wouldn't you?
