This bloke walks into a public toilet where he finds two cubicles, one of which is already occupied. So he enters the vacant stall, closes the door, drops his trousers and sits down. A voice then comes from the cubicle next to him "Hello mate, how`s it going?" Thinking this a bit strange but not wanting to be rude the chap replies "Yeh, not too bad thanks" After a short pause, he hears the voice again "So, what are you up to then mate? Again, answering reluctantly, and unsure what to say, he replies "Amm, just having a quick poo. How about yourself?" He then hears the voice for the 3rd time..... "Listen mate I`m sorry, I'll have to call you back, I've got some madman in the next cubicle answering all my questions"
