don't worry, be curry!

This curry sausage cart is on the market place of Halle every day. And they have rather delicious sausages.
The curry refers to the german currywurst wich is bratwurst cut in pieces with curry and ketchup on top. Also the german pronounciation for "Curry" rhymes with english pronounciation of "Worry". That's why they thought it's funny. Dunno, maybe it is.
There's also a clothing shop in the city called "Bonnie and Kleid" wich is a clever wordplay of "Bonnie and Clyde" since "Kleid" in german means skirt.
