Officially there is no sledging. Funny how upset the players get when the stump mics aren't turned off between deliveries..........I often wonder what they actually say when they go about their sledging in international teams ...guess we'll never get to know all that much about it, but your story sheds some light.
Ian Healey's sledge on Ranatungs was pretty memorable. Ranatunga called for a runner, supposedly because he'd hurt himself fielding. No-one was buying it except Ranatunga.. and the umpires. Healy pointed out "There's nothing in the rules about getting a runner for being a lazy fat c*^#". That one DID come over the stump mic.
When I played cricket, we seemed to spend more time sledging each other then the opposition. They were good times
