Another joke.

A farmer discovered that everytime he got ready for bed, he would find lots of pigs around, whats more, they were all infatuated with him. He was puzzled because as soon as he woke up and got ready for the day, they would all go away. One day he got annoyed and asked his wife, 'why do those pigs all keep hassling me only when I'm trying to sleep?'. She aswered, 'It's because you wear pigcharmers' (pyjamas)

That was so crap, but I couldn't think of a better way to use the pun.
