The Inbetweener

Me and my mate Brian were on the front row flying back from Slovakia. He the window seat, me the aisle one. We'd hoped nobody would be in the middle. Wrong!.... it was a full flight.

We chatted and often our chats were of a base nature. We debated, across our unwelcome companion, whether or not if one was bursting for a slash, it's a good idea to 'hang on' or relieve yourself. Clearly irritated, the man in the middle announced "Well, as it happens, I'm a urologist and I advise that if you need a piss, then piss off!"
