Vin Diesel has been captured by mobsters, who plan to hold him hostage until his hair grows in to show everyone that he is not bald, but rather he has hair and just pretends to be bald to impress everyone. OBJECTIVE: Infiltrate enemy base, shave Vin Diesel, get to extraction point.
Although, as I recall the Hostess ads, most of the time the actual crime they were comitting wasn't related to fruit pies, they were trying to rob a bank or something and Captain America would throw fruit pies at them and they'd give up or something. You could work this into an action scene, I guess, where the character gets in a fight with them only for the bad guy to realize he's not fighting, he's getting a really great shave.
