Not to me, but in the 1970s the family was on holiday in Malta and there was an extremely preening egotist staying in the same hotel who loved himself so much it was hilarious, In that less politically correct age, everyone referred to him as "Fairy". Anyway, one day we were sitting round the pool and he emerged in his designer trunks and proceeded to climb to the top of the high diving board. Once there, he shouted something rather too loudly to his friends to make sure that everyone noticed him, walked to the edge of the board, pulled his stomach in - and his trunks fell down. One of the funniest things I've ever seen...
