Paddy, Mick and Liam went for a few rounds of beer at a local bar.
Paddy says, “My local’s better than this. In my local, you buy 2 drinks and the third is free!”
Mick says, “Well, in my local, you buy 1 drink and you get the second for free!”
Not wanting to be outdone, Liam says, “That’s nothing. In my local, you buy the 1st drink…and you get the second, third, fourth, fifth and sixth drinks for free. Then you go out the back and get a shag!”
“No way!” says the other two, “Has that actually happened to you?”
“No…” says Liam, “…but it happened to my sister.”
