A man walks into a bar...
he walks up to the bar and says "gimme a pint", he downs this pint and walks over to a table where 3 lads are sitting.
He says to these lads "ive had ya mam"
they look at him and reply "piss off mate"
he returns to the bar orders another pint and also downs that.
he walks back over to the table of 3 lads and says "ive had ya mam"
they say "look, mate, piss off"
so he goes back to the bar downs a pint and walks back over to the table where the 3 lads are sitting,
he says "ive had ya mam"
one of them looks up and goes "dad you're drunk, go home"
