It might be fun to make a list of some of the weird things Jews do, but I'm worried we might get into an argument about the propriety of using the word "weird" to describe a divine commandment. So let's stick to the man-made stuff.
I'll get the ball rolling:
Girl-friend knitted srugies
(and how's that for some equal opportunity bashing?)
Hat-tip: A guy who used what might be his real name, but didn't tell me how to attribute him, or even if I should attribute him at all. If he gets back in touch with instructions I will update.
