My dad's a Jehova's Witness, but he's one of the cool ones; no door-knocking for him, and he's pretty open-minded too (Well, on most things. xP). I know what you mean though, I hate when they try and convert you... I already set on my religion, thanks. xD
But mine has to be WASPS! x(
I mean, I'm not too afraid if a bee flies past, but a wasp is deadly looking!
