QWP from miriku, who wanted me to add that it's from Numbers 22:30-32:
look, my choices right now are either unpack books or look up naughty words in the bible. if nothing else you now know that god thinks that if you smack your ass 3 times you're a pervert. i'm sure you'll put this knowledge to good use.
I'm still snorking out loud a little bit. Context is here.
