In Britain it's lucky for a chimney sweep to come to the wedding and kiss the bride.
The tradition stems from when King George III reigned. The King's horses ran out of control and a chimney sweep stepped in to save him. The King proclaimed, by Royal Decree, all sweeps were good luck bearers and should be treated with respect. Chimney sweeps are also linked with early pagan wedding rituals where the colour black symbolises fertility.

We do the same here in America only with the milkman....
