Funny you should ask - Yes Wash, I do remember it well - but as for how he got his name....its a long story
Let me take you back to the long, hot summer of 1999....we were 15 going on 16, and feeling like men of the world. (Needless to say, we'd done some good stuff, a bit of it on the right side of the law)....and there was a group of 4 of us who were quite close. Wash and I, you know, but then there two other guys...I can't remember their PdC names, or indeed, if they ever had them.....maybe not. Anyway, Wash and I were close, and the other two guys were close. We did a lot of the same things, as did they, and we met up to do a lot of the same things too.
Wash and I were in the top classes for subjects, so we spent a lot of time in each other's company, and the other two were less academically minded (And NO I don't mean that in a derogatory way, they just were...they're both successful enough now) and were a class or two down. Anyway, if anyone remembers a great session of WORMNerd Wash and I once had, we described a teacher in our school in a real time commentary of him becoming annoyed and throwing people out of where they weren't supposed to be (rightly so). He was a strict, but fun enough English teacher who taught our two friends.
Now, we were doing A-Levels, and went to a local sandwich shop for our lunches. It turned out to be the downfall of our group, actually, because they started doing other things and we gradually grew apart the way friends sometimes do....anyway, sometimes we saw the teachers down at this sandwich shop....sometimes we even bought their lunches.
From here, the story is actually made up to fit certain facts I know, and Wash might tell me its purely fictional.
The English teacher was involved in some pie-buying scenario that surprised our friend in its volume. With their paths crossing frequently - in English lessons - our friend's ribbing (it was just a bit of fun) became commonplace, and amongst a group of 4 of us, he became the Pie-Man of lore. He wasn't particularly fat, and he was quite a nice bloke.
I think that covers it....fairly.
