How to get free drinks?

Shamus and Murphy fancied a pint or two but didn't have a lot of money between them, they could only raise the staggering sum of one dollar.

Murphy said "Hang on, I have an idea." He went next door to the butcher's shop and came out with one large sausage. Shamus said "Are you crazy? Now we don't have any money left at all!"

Murphy replied "Don't worry - just follow me." He went into the pub where he immediately ordered two pints of Guinness and two glasses of Jamison Whisky.

Shamus said "Now you've lost it. Do you know how much trouble we will be in. We haven't got any money!!"

Murphy replied, with a smile "Don't worry, I have a plan, Cheers!" They downed their drinks.

Then Murphy said "OK, I'll stick the sausage through my zipper and you go on your knees and put it in your mouth." The barman noticed them, went berserk, and threw them out. They continued this, pub after pub, getting more and more drunk, all for free.

At the tenth pub Shamus said "Murphy - I don't think I can do any more o' this. I'm drunk and me knees are killin' me!"

Murphy said "How do you think I feel? I lost the sausage in the third pub."
