Knock him out

You creep up behind Mr. Milken's while he is washing his hands and knock him over the head. He falls with out much resistance. You quickly strip him of all his clothes and put them on... all but his boxer briefs, which you let him keep, since you could just go commando. You don't want him getting fired for public indecency after all. You quickly move him into the stall so that no one will find him before he wakes up. You need to figure out how to get back to looking like your old self.
