Moisha Rabinowitz in the late 1930s fled his native land of Germany.
He sold all his assets and converted it to gold and then had 5 sets of solid gold false teeth made.
When he arrived in New York the customs official was perplexed as to why anybody would have 5 sets of gold teeth.
So Moisha explained: "We Orthodox Jews have two separate sets of dishes for meat products and dairy products but I am so kosher and religious I also have separate sets of teeth."
The customs official shook his head and said, "Well that accounts for two sets of teeth. What about the other three?"
Moisha then said "Vell us very religious Orthodox Jews use separate dishes for Passover, but I am so religious I have separate teeth, one for meat and one for dairy food.
The customs official slapped his head and then said, "You must be a very religious man with separate teeth for food and dairy products and likewise for Passover. That accounts for four sets of teeth. What about the fifth set?"
"Vell to tell you the truth, once in a while I like a ham sandwich."
