I've taken notice of several interesting and unique phrases of swearing and cursing. In addition to the usual "blooming" for bloody, "geez" for Jesus, and "rats" for who-knows-what, Socrates swore "by the dog" and Pythagorus swore "by the number 4."

What do some other cultures/languages swear by? (please forgive the sentence-ending preposition)

Awaiting some responses that will shiver-me-timbers.
