Wikipedia says that the occupation of chimney sweep "is considered to be one of the oldest in the world," along with, I guess, the other obvious one that comes to mind. Wikipedia also says that in parts of Great Britain it is considered lucky for a bride to see a chimney sweep on her wedding day. It is also considered good luck to shake hands with a chimney sweep or to be blown a kiss by one. Here it's considered good luck to rub one of your buttons if you pass one in the street. This fellow was selling little key chain brushes (100 dinars=$2.00), so I bought one. And he let me take his photo, though he didn't blow me a kiss, darn.
Note: "Srećna" means both "happy" and "lucky" here, so I think his shirt should really be translated "Lucky Brush," since chimney sweeps bring you good luck...or maybe he really is just happy when people buy a keychain brush from him...
