there was a wonderful story in Germany several years ago of a couple in a Volkswagen Beetle and she "froze" on him, unable to separate.....
The Fire Brigade were called - apparently there was no medic around with a relaxant to inject into them to enable the separation or their angle was such that they were well and truly clamped onto each other and they couldnt get in close enough.
Anyway the Fire Brigade cut in through the back and peeled the car roof back as if it was a sardine can.
The couple were lifted out and the separation achieved, the woman bursting into tears in reaction.
"It's ok dear, you are safe apart now."
"It's not that, how am I going to explain the state of my car to my husband..."
