I have seen lots of these popping up on the web, especially some of the facebook posts of the teams in the states. Harry Soo has actually starting showing people how to do these in his BBQ 101 classes.

Sense of Humor: Radio Prunes rendition of macbeth is right up there, Lee Evans-stand up, Mitch Hedberg, Monty Python, Horton hears a Who, High Spirits staring a very pissed Peter O Toole, anything clever and well delivered. Not too keen on the innane and idiotic.
I'd cook some for Sica (my partner) but she'd instantly jump to the conclusion that there had been an accident involving her pet tortoise and that I'd tried to cover my tracks with a bit of sneaky BBQ misdirection.
