"The Soup Spot", a soup shop I often go to in Manhattan (on 31st, across the street from Madison Square Garden) has had some fun with the Soup Nazi idea.

A few weeks ago, their workers started wearing caps, that said "Yes, Soup For You!". Pretty funny (to me anyway).

By the way, this place is extremely good and inexpensive (by Manhattan standards). They have 8-10 different soup choices a day and a 16 ounce cup is $4. You get some bread and a piece of fruit with it as well. Not sure where else you can get a lobster bisque for $4 in Midtown.
