Bar Hopping

Two drunks were trying to figure out how to get some alcohol for free. They only had a dollar in change between them.
"I've got it, follow me." said the first man. They went to a hot dog stand and bought a dog and threw away the bun. "We'll go into a bar and order drinks, and when the bartender asks for money, I'll unzip my fly and pull out the hot dog. You drop to your knees and pretend to suck me off."
The second man agrees to this and they start their rounds. When they get to the bar, they sit down and have a beer.
The bartender tells them, "That will be 3 dollars."
The first man stands up and upzips his fly. The second man drops to his knees and starts sucking on the hot-dog.
"You faggots!", screams the bartender. "Get the hell out of here!"
They run out and go to another bar and order drinks and when the bartender asks for money, the first man unzips his fly, and the second man drops to his knees. The bartender throws them out.
After the sixth bar the second man complains, "Man this isn't working out so well, My knees are killing me!"
"You think you've had it bad..", the first man exclaims. "I lost the hotdog 4 bars ago!"
