My favourite piece of Wimbledon commentary so far:
1st commentator: " - blah blah blah playing possum.....Do you have possums in this country?"
2nd commentator: "No, we don't."
*pause*
1st C: "Well it's a sort of defence mechanism, they pretend they're dead."
2nd C: "....it doesn't mean I don't know what a possum is, just because we don't have them in this country, but thank you for insulting me."
