It's not funny - why do we laugh when tickled?

I HATE being tickled, but on those rare occasions where someone gets the better of me and commits tickling, my physical reaction is laughter. I am not enjoying myself, it does not feel good, and in fact I am getting more and mor furious by the second, but I’m still laughing. What the heck kind of goofy-ass reflex is this, anyway?

A partial answer seems to be… no one is sure.

The Master speaks.

Leave it to me to find a question no one knows the answer to.

Crap.
