LOL... That's clever.. If I tried that I would probably end up smashing the bottle

Slick 

Bloomin' heck Supes. Thats handy to know.

Haven't tried it, but may be a handy hint in an emergency
Just found a version in English:

I didn't know that. Useful information.
I suppose, though, that if it is a wine with sediment the tapping of the bottle is going to disturb that sediment, and you would then face a long wait until the sediment settles again.

Hey Super     - look at our Forum Posts numbers.      Snap! 

I ain't doin that with my Louboutins

Oooo, forum twinnies

blimey thats clever

I do think it's rather a handy tip should you be in the company of a gentleman with good shoes but do not have a bottle opener

Most wine bottles have a screw top now. If you want to open a bottle of Newcastle Brown however and don't have an opener, there's always the door lock.
