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 going?"
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*ckhead in the loo next to me answering everything I say."
