Oh dear Moyel jokes-- they are (or have been) rampant in NY

-like the person who is traveling in (any remote place in the world)- and his watch battery dies-- walking down a small street, he see a shop with a large pocket watch hanging out side.

he enters the store, the shelfs are dusty and bare, but a well dressed man appears from the back of the shop-

the traveler only speaks english (well this is an american joke!) and starts to speak to the shop keeper, hoping that in spite of the scant visible stock, he will have a battery.. the shop keeper keeps trying to stop the man, but he persist in asking-- Till finally, the shopkeeper explains-- I am not a watchmaker, this is not a watch shop-- i needed some space, rented it, and never removed the watch from the previous tenent...
So the man asks-- why not, why don't you advertize what you do? the answer "I am a moyel-- what do you suggest i hang outside?"

Most of the other moyel jokes are just too well, not appropiate! (many are very funny!)
