Irish pub joke

[Chris H]

Mick in a pub bragging to his mates. "In my local you buy two drinks you get the third free"

Seamus replies, "That's nothing, in mine you buy one and get the second free."

Pa! says Paddy, "I know a pub where you get the first, second, third, fourth, fifth, sixth and seventh drinks free!"

"And not only that but afterwards you can go round the back and get a shag for free!"

"Is that what happened to you?" ask the other two.

"No" says Paddy, "but it happened to my sister!"

Heard that in about 1986 but still makes me laugh
