I like bottle caps because you can open them with anything, and everyone thinks your cool (guaranteed) when you pop em open with a knife or spoon or something. I smashed a wine bottle when I was younger and stupid(er) trying to push a cork into the bottle, blood and wine everywhere.
Corks are for the sort of wankers who like to use their knowledge of outdated notions of etiquette to belittle the ordinary people.
Caps are for drinkers.
