(Apparently) True Story
The scene: Australia v Zimbabwe Cricket Match
McGrath was bowling to Eddo Brandes, the portly Zimbabwean. First he was nicked over slip for 4 and next was slashed through cover for 4. McGrath glared at him and said “Why are you so fat?” to which the quick and very Zimbabwean style reply came, “Because every time I fuck your wife she gives me a biscuit”. Apparently all the Aussies were rolling around with laughter.
Thanks Shaf!
