Fred and Ray go to the liquor store to buy a cheap bottle of booze. Once in the store, they discover that they only have $1.50 between the two of them.
Ray says "I've got an idea" and goes next door to the butcher shop and comes back with a polish sausage. "here Fred, stick this in your pants, I know how we can drink all night for free".
"What the hell, Ray? Now we don't have any money!". "Don't worry, we'll go to the bar, order some drinks and when the bartender asks us to pay the tab, you stand up, unzip your fly, pull out the sausage and I'll start sucking on it".
The two blokes walk to the nearest bar, sit down and order two beers and two shots of whiskey. They down the drinks and order another round, drink those and order another. After the third round the bartender asks them to pay up. With that, Fred stands up, unzips his fly and Ray leaned over and proceeded to suck sausage.
"What the fuck are you doing? Get the hell out of my bar!" says the bartender, the two run out laughing.
"That was great, and it didn't cost us a cent" says Fred. "Let's do it again!"
So off they run to another bar for a repeat performance. This continues through the night.
At the end of the night, after about the 12th bar, Ray says "Man, I'm starving. All that beer made me hungry. Hey, pull out that sausage and let's eat it".
"Sausage?" says Fred "I ate it four bars ago!"
