The log has to be fully formed though. The first time a Grand Slam happened to me was in Chatham after a call round to see my mate Dhobey Bucket. I cleared my pile of tinnies and then had to go ashore with the reprobates from the Snakey. I don't think we'd
got very far, possibly the Army & Navy, when I had to go outside for a tactical vomit. Unfortunately the rest of my orifices let me down, and I had to ditch my knicks, purely as a health and safety issue you understand, and shoot through on the lads.
Boy, was my name mud, but you can see why the option of giving my Y fronts a dhobey was never going to happen.
