An Irishman approached the foreman at a job site to ask whether work might be available.

“I note you’re Irish,” said the foreman.

“Aye,” said the Irishman.

“Well, if you want to work in construction, you have to tell me the difference between a girder and a joist.”

“Aye,” said the Irishman.  “Girder was German and Joist was Irish.”
