Mammals are leading 10-0 at half time.
The bugs bring on a centipede as a half time replacement.
Immediately a lion runs up the middle and is stopped dead by a crunching tackle from the centipede.
Minutes later a greyhound is hurtling for the try line when the centipede pole-axes him with a spectacular cover tackle.
A hat-trick of tries follows from the centipede and the bugs are victorious.
"Flippin' heck" says the lion says after the final whistle, "why weren't you playing in the first half ?"
"I was getting my boots on," replies the centipede.
