Funny Irish Joke - esp. for you, Irishree

Actually, I've heard this joke with a number of nationalities, but in honor of St. Patrick's Day.........

Mick O'Flaherity was stopped at a petrol station out in the the countryside when he noticed two laborers slowly working their way towards him on the other side of the road. One was digging a hole, then the other would fill it in after setting a bit of concrete at the bottom. They really didn't seem to be accomplishing much, so Mick strolled on over to find out what they were doing.

"Say, there," he called out. "What's this the two of you are doing? It doesn't make any sense."

O'hara stopped and leaned on his shovel. "Sure and I'll be tellin' tha.  Fahy here and me, we're puttin' in some new telephone poles. And I'll have tha know we're the best crew in the County. I dig the holes, O'Flynn sets the pole, and Fahy fills in the hole."

"But, there aren't any poles and there's just the two of you. This is nonsense!"

"Ah, well, tha knows O'Flynn's out wit the bug today." Fahy now comes up after tamping in the last hole and joins in. "Aye, that he is, that he is. Right sickly. But O'hara here and me, we're feelin' fine. Now, tha wouldn' ha' us sit around and not do our jobs just because O'Flynn's under the weather!"
