We had a lad work for us a few years back who somehow managed to qualify, despite his incredible stupidity. Were down the docks, doing a galv tube job, and he comes up and says "Where's the 25mm Galv box lids?" "Pardon...?" "The 25mm Galv box lids??? I can only find the 20mm..." This was a lad who was a good year or so out of his time. Anyhow, we tells him that the big boss man would be down shortly and he always has some in the boot of his car. "Ok, have to wait then won't it." True to his word, boss man turns up in his BMW M5, this lad trotts on up... "Alright boss, you got any 25mm box lids in the boot?", he takes a glance at us, looks back at him, passes him the keys "There is definately a few in there somewhere, have a good look."
When I was a 1st year, the lad a year ahead of me was a bit simple, so he used to get the brunt of it. The day before Christmas eve, only a few guys in on half day, Foreman brings in a big old quiz. Goes around asking dead simple questions, "Whats the capital of Ireland?" "Who won the cup in 76'?" (thats rather easy around here) until he come to this lad... "Whats the scientific symbol for Silver in the Periodic Table?" - "Ummmmmmm... Ummmmmmmmmm... Errrrrrrrrggggghhhhhh.... I don't know Pete." "YOU WHAT!? GET DOWN AND GIVE ME TWENTY!!!" and he did. And they continued until this apprentice must have done 250 press ups, and didn't once question why everyone else was getting the simplest of questions. He never did make the grade.
