A man walked into a public toilet where he found two cubicles, of which one was already occupied.
So he entered the other one, closed the door, dropped his trousers and sat down.
A voice came from the cubicle next to him:
"Hello mate, how are you going?"
He thought it a bit strange but not wanting to be rude he replied
"Yeah, not too bad thanks."
After a short pause, he heard the voice again
"So, what are you up to mate?"
Unsure of what to say, he reluctantly replied
"Umm, just having a quick poo... How about yourself?"
He then heard the voice for the third time ......
"Sorry mate, I'll have to call you back . I've got some moron in the loo next to me answering everything I say."
