Failure at every turn. Perhaps the funniest episode of a serious show I've ever seen. 'There's no 'E', John'. 'There are only two 'E's', John', 'There isn't an 'A', John'.
At one point it takes him a properly agonising 10 seconds to choose a letter.
In one of the many rounds he lost his word was 'GRANT', the only reason being that the letters came out something like 'XDEFGRANT'.
His family must have sent him on a bus down to Countdown because they couldn't afford to stick him in a home.
edit - The woman he was playing had a bit of a shocker as well after Oor John had already failed miserably. The nearest she got was 100 away from the correct number, although it was just a mistake. Then in the final numbers game Oor John was 7 or 8 away. I mean, what's the fucking point?
