I'll throw out one of my attempted sledges on the field... It's a bit fuzzy but I'll try to remember.
Was playing against one of our rivals, got heated. Half-time was called, about 5 after half-time they got a try (wrongly) disallowed, we were having a good laugh. One of their big Kiwi boys was yelling and screaming at us, calling us "pussies", "********s" etc...
One of our boys said to him "Why is he so mad?", which I loudly and obnixiously said "You'd be mad to if you couldn't pronounce your vowels and always had to go to a Fosh and Chep Shep (Fish and Chip shop)"
Needless to say next run, he found me, and slammed my head in to the ground like it was a basketball. Got a wicked concussion and a busted up face.
Was it worth it? I dunno, haha.
