Hi Dave-O,
Nice to find someone else with nothing to do on this most auspicious of days - and not a bad joke either.
The previous one reminds me of the bloke who was convinced his wife was having it off with the milkman, so spied on his house after leaving for work one morning.
Delighted to see the milkman arrive, leave the milk and immediately go back to his float, he rushed back home to find the wife at the sink, washing up. He approached from behind, stuck his hand between her legs to hear her say "Two loaves and a crusty please, baker".
