I don't ever want to know why Australians have inflatable kangaroos...
Hah! Gonna tell you any way!!!! Aussie bowlers use them as target practice in the nets prior to Test matches with the Poms... a pommie batsman's face is taped to to the head and..... well you get the picture.
***wonder if Kiwi cricketers use inflatable sheep instead
What's worse is where the port to fill it with air is
So what you're saying is that you wouldn't be seen dead in public blowing one up!
