obscene jokes are supposed to be racist jokes!
ugh... oh well.
Okay, so there was this Jew rabbi who kept all the foreskins from his bliss. when he was about to retire, he wanted to do something with all that skin. so he goes to a leather craft shop and says to the craftsman "Can you make a really big bag out of all this skin?" and the craftsman says "Sure. please come back in a week."
next week, when the rabbi came back to pick up the bag, the craftsman gave him a very small pouch. the rabbi got angry and said "I told you to make a huge bag for me! and how could it be so small when i gave u that much skin?" then the crafts man says "No worries, just rub it a little and it will be the right size"
