Hope this one is not too ruude!
Why men don't talk to each other in public toilets

The other day I needed to pay a visit, so I found a public toilet that had two cubicles.

One of the doors was locked. So I went into the other, one, closed the door, dropped my trousers and sat down.

A voice came from the cubicle next to me: 'Hello mate, how are you doing?'

Although I thought that it was a bit strange, I didn't want to be rude, so I replied 'Not too bad thanks.'

After a short pause, I heard the voice again 'So, what are you up to?'

Again I answered, somewhat reluctantly, 'Just having a quick poo... How about yourself?'

The next thing I heard him say was ...... 'Sorry mate, I'll have to call you back. I've got some d******d in the cubicle next to me answering
everything I say.
