Nice one!
The thing that was so funny about the missus saying that at that particular time was that it was at least 3 years since I'd told her of the infamous "drop bears" and it had never been mentioned since then! I had to stop the car. She thought I was choking or something.
I'd told her that they lurked in trees by the side of the road, and that as you drove past, they leapt from the trees and ripped your tyres off as you were driving along!
