Shamelessly lifted from reddit:
An Irishman goes to a building site for his first day of work, and a couple of Englishmen think, “Ah, we’ll have some fun with him!”
So they walk up and say, “Hey, Paddy, as you’re new here make sure you know a joist from a girder…”
“Ah, sure, I knows” says Paddy, “twas Joyce wrote Ulysses and Goethe wrote Faust.”
