A man went into the public toilets to relieve himself. The first cubicle was in use, so he went into the next one. As he took down his trousers, he heard a voice from the other cubicle.
"Hey, hows it going?"
Not wanting to be rude, he replied, "Not too bad thanks."
A few seconds later, he heard the voice again.
"What are you up to?"
Somewhat relunctantly, he replied, "Having a quick sh*t, what about you?"
He heard the voice again. "Hold on, I'm going to have to call you back."
