The Kama Sutra and other worldly advice

Wouldn't you know the Kama Sutra actually has some sage advice within its position-ridden pages? Apparently, the Kama Sutra, while condoning hundreds of sexual positions and abnormalities from scat-play to "fetch", advises against one thing... NEVER HAVE SEX IN A HOT TUB

Gee, I wish I knew about that before yesterday :\
