Have you ever gotten concussed?

Just asking. I was playing Aussie rules football and I got knowcked out, and still don't know how, and when I woke up I was walking along the half-back flank, and I thought I was dreaming because I didn't know how I got there. Anyway, my hand-eye coordination was out of whack so when I went for the next tap I completely stuffed it and got myself a corky, and so went to the bench because of that, and the classic quote was "Um, mate, what team are we playing for?", cause though I could remember all the people, I couldn't recognise the jumper, or where we were playing... Anyway, what about you?
