Three boys are enjoying a quiet night in a pub, when a man stumbles in and orders a beer.
Spying the group, the drunk stumbles over, points at one of the boys and shouts: ‘I’ve fucked your mum!’
The lads ignored him and returned to their beer.
He shouts again: ‘Up the asssss!’
Although irritated, they ignore him again. The drunk stands up again points at the boy and yells: ‘Your Mum’s sucked my cock!’
The boy looks up wearily. ‘You’re drunk, Dad. Go home.’
