Watch in mild horror as a Manchester United fan drinks his own urine having pledged to do just that if Louis van Gaal was still the club’s manager for the home game against Chelsea.

Séamus Bannon clearly wasn’t taking the piss when he tweeted the following prior to last week’s 0-0 draw at Old Trafford:

@MUFC_today If LVG is manager of our beloved United at the Chelsea game, I will drink my own urine. #MUFC

Unfortunately for him, taking the piss was precisely what he had to do when a Liverpool-supporting friend held him to his word.

Valuable lesson learned, you’d imagine.
