Yep I watched him pick up a bottle clearly labelled cif sink cleaner, I watched him apply it, clamp it etc. And then waited. 30 minutes later he came to see me. Sir my woods not gluing. I asked him what he used. He said glue. I told him to get me the bottle. Then I told him to read it. He read it, I asked him, why do you think its not stuck? His reply.......I don't know. I can teach monkeys to make high quality furniture, but I can't combat stupidity....which is generally passed down from the parents
