Another academic poo story

While a mate was at Imperial College many years ago he was in the Union Bar and in strides the College Loony. "If I crap in my pint of Lager and then drink it, who's going to buy me another pint?" Many hands go up, so Loony buys himself a pint, gulps a third of it to make room and then heads for the basher. A couple of minutes later he returns proudly brandishing his glass with promised floater standing therein. A few seconds later the deed is done, and those that haven't run to the basher clutching their stomachs and/or mouths are buying the drinks as honour demands. As a grand finale / encore Loony eats the turd before starting on the free lager. It was of course a mars bar but I'd defy anyone to tell the difference after a couple of minutes immersion in watery college beer.
