Australian cricketers back in back in the 80's / 90's were great with sledging the opposition batsmen with lines like ,"I fucked your mother last night " or" your wife gave good head last night" usually got the bloke out in the next few balls.
Rod Marsh & Ian Botham:
When Botham took guard in an Ashes match, Marsh welcomed him to the wicket with the immortal words: "So how's your wife & my kids?"
Botham retort was "Wife is fine, kids are retarded"
Glenn McGrath (bowling to portly Zimbabwean chicken farmer Eddo Brandes):
"Hey Eddo, why are you so fucking fat?"
Eddo Brandes: "Because every time I fuck your wife, she throws me a biscuit."
I hate my sister in law. I think it's because she's the female version of me. But, as much as she repulses me, as much as the sound of her voice irritates me, I must admit, she has an arse that I would love to bury myself balls deep into.
