I think there must be a law derived from Murphy's Law that says that if you advertise a language school or a language course, the chances of making a typo or an unintended double entendre are quadrupled.

I do know Skitt's Law, which states that any Usenet or message board post designed to point out a spelling or grammatical error will itself contain an error, generally even more humiliating and/or hilarious than the original. I've fallen fowl -- er, I mean, foul -- of that one more than once.
