Stephen “Yabba” Harold Gascoigne (born March 19, 1878 in Redfern, Sydney- died January 8, 1942 in Lidcombe, Sydney) was an Australian sports fan, well known as a heckler at Sydney Cricket Ground cricket and rugby league games in the early part of the 20th century. Yabba was known for his knowledgeable witticisms shouted loudly from “The Hill”, a grassy general admissions area of the SCG.

“The Hill” area was replaced with seating in the early 1990’s. The new stand was then formally named Yabba’s Hill in honour of his colourful comments, several of which have passed into cricketing folklore.

Some of Yabba’s best remembered insults include:

“I wish you were a statue and I were a pigeon.”
Telling a fly-swatting English cricket captain, Douglas Jardine, to “Leave our flies alone. They’re the only friends you’ve got here.”.
“Send ‘im down a piano, see if ‘e can play that!”
“O for a strong arm and a walking stick!” (at bad bowling; leg spinner Arthur Mailey, a regular victim of this one, quotes it several times in his book 10 for 66 and All That)

Yabba; legendary Aussie sledger. Used to be around in the 1920s/30s, ended up having an area in the SCG named after him (Yabba’s Hill, and I believe the only non-player or patron to have such an honour).

Just seen. Not much for the BA to fear on this evidence.

I hate to admit it but the Barmy Army are great entertainment. I sat behind them at the MCG test when the Waughs were still playing and all I can say is that we’d better come up with something bloody good to tackle them head on. There’s nothing more embarrassing than hearing the Poms in full song and the best response we can come back with is the (in comparison) moronic “Aussie, Aussie, Aussie”. Cant wait for the Ashes to start though….

First of all, remember Gatorade is just another yank company trying to make a fast buck.
Second. We don’t chant and sing at the cricket. The only reason the brits do is because they’re segregated at the “football” and the rugby union (swing low sweet chariot etc) so they can get a choir happening.
The tradition at aussie footbal is just to yell out whatever comes into your head, not what everyone else is shouting out.
Three. The sad thing is the barmies just sing all day, don’t get to meet any nice aussie girls, don’t get to experience great aussie hospitality because they’re already pissed after the cricket and can’t get into any decent pubs dressed as boys in all their flag crap.
I do feel sorry for the pommies who paid hundreds for their tickets and the tickets have been withdrawn!
