Best way to remove a bottle cap?

My favorite trick is using another bottle to open a bottle.

Rings. I'm married and have a tungsten ring, so it's basically always on my hand. Some bottles don't give you much room to get under the cap, but I can get most anything open pretty quickly.

During my fraternity days, I would often say, "the world is my bottle opener" just before using some random object to open a beer.

All that really matters is if its sturdy and small enough to catch over your knuckle and under the rim. Literally any object like that will work.

Lighter. I smoke, so I always have one handy.

Best/portable: Bottle opener keychain, most alcohol shops will give you one, there's usually a beer doing a promo with them, just ask them because they probably have a box they keep forgetting to give out.

Creative: probably lawnmower.

Cap against edge of concrete ledge. My friends and I bought a bottle of cider at a 7/11 and realized we didn't have a bottle opener. Cue that moment of brilliance from my mate.

Angle just the cap onto the edge of a table and pound it with your fist. Results not guaranteed

I keep a corkscrew in my purse. It’s just nice to have

Learn from my mistake.

Don't use a knife as the lever.

Doubly so if you're already intoxicated.

Just because its theoretically possible does not make it a good idea.

Car door latch. Fence bracket.
