Some to avoid more likely. Just don't let some idiot carried away.
There was one in a rural area where the bridroom was symbolically castrated with a rubber band. Only he was too drunk to wake up. His introduction to marriage involved loosing the function of his genitals.
On my brothers stag night, every time he said 'cheers!' (which he says a lot in place of thank you; goodbye, etc as well as when clinking pints) he had to drink a sambuca. Then, on his big day, during the best man's speech he was presented with a large sambuca after his best man set up the relevance in a couple of lines.
. Raised a giggle or two, although I was a bit worried my brother might vomit when he had to down it!
