Why did this gentleman put a chainsaw in his pants?

It's not clear why this fellow put a chainsaw in his pants. Was he succumbing to an unspeakable urge? Was he providing ill-advised self-treatment for pruritis of the groin? Was his bladder filled with gasoline and he was simply filling the chainsaw's tank as a pay-it-forward gesture for the person who buys it? We'll probably never know the truth, because he walked out of the store with the chainsaw still in his pants and has not been seen since.
