So there's two Irishmen named Paddy and Fitzpatrick and they're a real pair of boozehounds. One day, Paddy tells Fitzy that he's come up with an ingenious plan to never have to pay for a drink again.
"So out with then Paddy" says Fitzy
"Right boyo, this is what we do. We'll buy a salami with our last money and then head into a pub right. Then, when we've had our fill, I'll whip the salami out my pants, you jump off the barstool and proceed to give me what will look like a BJ. The barman gets angry and throws us out and bingo, we haven't paid for the drinks" says Paddy
"Oh Paddy, that's real clever that is, let's get going" says Fitzy
So off they go to put their plan into action. They sit at O'Malleys for 3 hours drinking when suddenly Paddy whips out the sausage and Fitzy gets down to business. The barman promply chucks them out and off they go thinking how good the next few weeks is going to be. Months pass with the same results and life for the drunkards seems awesome. Then one day Fitzy asks Paddy,
"Mate, do you think we can maybe do a change where I use the salami and you get down on your knees?"
"Why Fitzy, we've got a good thing going" says Paddy
"Well, it just that my knees are shot from always jumping to the floor" says Fitzy
So Paddy says, "You think you have something to complain about, I lost the damn salami weeks ago!"
