OK, here’s a clip from the Rankin Bass special where Charlie in the Box shows up. Ever wish you could explain to him that the problem might not be his name, so much as the fact that he comes across like the kind of guy who’d get arrested for exposing himself on public transportation systems?

First of all, when you think about it a little, the name “Jack In The Box” has far worse connotations.
Second of all, Tom, you need to get out more … yeah, so do I.
Yeah, “Jack in the Box” does sound worse, doesn’t it? But again, the name is SUCH a miniscule part of the problem. “Ooooh! A present! What is it, Daddy? Is it that Playstation I asked for?” “Nah. This year, I thought I’d get you a creepy man who jumps out of a box at you.”
Not going to be a very merry Christmas morning in THAT household!
