"The Fight!" joke

Kelly limps into his favorite pub...

My god! What happened to you?" the bartender asked Kelly as he hobbled in on a crutch, one arm in a cast.

"I got in a tiff with Riley", whispered Kelly to the beertender.

"Riley? He's just a wee fellow," the barkeep said surprised.
"He must have had something in his hand."

"That he did," Kelly said. "A shovel it was."

"Dear Lord. Didn't you have anything in your hand?"

"Aye, that I did - Mrs. Riley's right tit." Kelly said.
"And a beautiful thing it was, but not much use in a fight!"
