The caption should have been
about how the person is now suited for promotion to [sales manager, marketing, VP of whatever, etc.]
a threat to remove other body parts.
some sort of Wizard of Oz reference..
"Jesus Christ! What an idiot!"
about Dick Cheney shooting that one guy in the face.
about the nifty painting in the background.
about something else which will go in a comment.
And while I'm at it, here's this month's Cartoon Caption Contest.
My question here is simpler.
Will one of the finalist's captions be a joke about how the policeman wants a giant doughnut just like one the caveman has?
I hope so!
I hope not.
