Well you see Watson, the case is simple.

Naturally, following the laws of cinema it was the butler that did it. However if there’s more than one butler in contention for the “evil” butler, the one with the least hair did it (provided he isn’t jacked, see the “Rock” constant).

Now, utilizing my understanding of the Luthor principal of bald-to-evil correlation I can scan this crowd and conclude who the culprit was. Henceforth, I posit that it was the singular bald bulter on the left who did it, he is neither jacked nor tied with anyone else for having the least hair and is thus unquestionably guilty.

Thank you, thank you, I’ll take my fee by check.

It’s the gardener. It’s always the gardener
