ok - from memory (I couldn't find any clip or evidence thus far), as I remember seeing it myself, Taylor, who played several games that season, needed one more appearance to be eligible for the champions medal (think it was 10th appearance?). AW made 2 subs already, and he was getting ready to come on as a third. I don't remember exactly how it went, but I think the game wasn't safe yet, and Freddie came off the bench looking serious as if he was really coming on - Taylor almost lost it, until Fred revealed the joke. I think it was the Everton game, but I can't swear on it.
BTW, the Parlour -Keown story seems right (though I don't remember it myself) - from Vital Arsenal:
Another of his more public pranks occurred in the last match of the 2003-04 season. Martin Keown needed one more appearance to secure a league winners medal and Arsenal had one substitution remaining with four minutes left to play. Parlour and Keown were the only reserves left. With Keown warmed up and primed to tick the numerical box, Parlour jokingly began to warm up too, upon running past a bemused looking Keown, Parlour told him, "Boss told me to warm up, I`m coming on." It was left to Keown to approach Wenger and gently remind him of the small matter of his much needed tenth appearance. The look of relief on his face when he discovered it was a prank was captured for all to see.
