Intellectual Paddy

An Irishman turned up on a building site looking for work. He was directed to the site manager who agreed to take him on if, after a tour of site, he could answer correctly a few questions. Twenty minutes later they were back at the office. 'Well,' said the site manager, 'you have seen what we do here. Now, I'll take you on if you can just tell me the difference between a joist and girder.''Ach, that's easy enough', said Paddy. 'Joist - he wrote "Ulysses", Girder, he wrote "Faust".'
