Stone the flaming crows!
2 crows were sitting on the powerline when an F111 went roaring over going flat out.
The 1st crow picked himself up off the ground and said "Strewth - what the heck was he going so fast for?"
The 2nd crow replied "Well you'd be going bloody fast too if your arse was on fire like his!"
This joke may be old as the hills but it's still a bloody bewdy LOL
