I was in the public toilets today and as I sat down, a voice from the next cubicle said "Hi, how are you?".

Embarrassed, I said, "I'm doing fine". The voice said "So what are you up to?". I said, "Just doing the same as you - sitting here! He said "Can I come over?". Annoyed, I say "I'm rather busy right now". Then the voice said, "Listen, I'll have to call you back, there's an i.d.i.o.t in the cubicle next to me answering all my questions".
