What? Ever? Broad question, but here's what I'm thinking off - today anyway...
Funny? Hmmm, I remember Stuart MacGill getting a wicket and tossing the ball over his shoulder in nonchalant celebration and it happened to hit Jason Gillespie in the face as he ran in to congratulate Stuey - he was not expecting a ball to be coming his way. That made me laugh loudly. And Glenn McGrath coming in at #6 for the World XI in the Tsunami match, I couldn't stop laughing. In fact I was still laughing when he holed out 2nd ball.
Favourite serious moment? Probably some from the 06/07 Ashes: the last day at Adelaide, Warney bowling Strauss for 700 wickets, Gilly tonking Monty all over the WACA and the 5-0 vengeance in general.
And the 1999 World Cup semi-final of course. Great game.
Voges' catch last summer was pretty cool too.
