In a perfect universe all bottles would be twist tops, but alas for some reason (sanitary?) some bottling companies insist on making you seek out and employ the use of a third party opening device.

Being the DD is usually the most boring job at the party, so why only be useful at the end of the night? Keep the keys and open the bottles for everybody. Note: this works for non-alcoholic beverages as well.

Never open a bottle with your teeth again! This handy little bottle opener from Suck UK inauspiciously sits amongst your other keys, patiently waiting for the call of duty.
