Paddy and his wife are lying in bed one night whilst the neighbour's dog barks through the night in the garden next door.
Paddy says, "I've had enough of this!" as he storms out of the house at 1am in the morning.
5 minutes later he comes back upstairs looking rather pleased with himself. "What have you done?", his wife asks.
"Put the dog in our garden... see how they like it"

I don't know why, but I found that funny.
