The brit new teeth trick

I took a bottle of rum refresher from the company's fridge. Barcardi breezer. Tropical peach. All chilled and ready, I'm all thirsty for it; except for one thing, I can't open it without an opener. So I went searching into my next door company.

Its lucky I bumped into Ben, someone I worked with. I didn't realise these british boys have some old school trick. He could open the bottle with his teeth, my, I want to learn that!
