An English navvy goes after a job on a construction site. The Irish foreman says, "I'm sorry. You look a strong capable lad but I'm only allowed to employ Irishmen."
The Englishman, not to be thwarted, claims to be Irish.
"No way", says the foreman. "You sound English."
The Englishman tries a different tack. "I realize it sounds unlikely but my name's Dare, I was born in County Clare, but I've worked over here so long I've started to sound like a fokkin Brit."
The foreman ponders for while. "Dare's a good Irish name, but... No, no. I've got a good crew here and I don't want to risk any trouble. Sorry."
The Englishman plays his last card. "Will you accept me if I can prove some of the chaps out there know me?"
"Sure", says the foreman, who doesn't really want to turn down such a capable looking worker.
They step out of the site hut and the Englishman tips back his head and calls out to dozen or so men working high up on the scaffolding.
And at least half of them pause, look down, and shout back, "Hello dere!"
