Did the koreans just wake up one day and think "you know what would be cool, a drink with the top of a can and the bottom of a bottle. It'll mess people up"
"you know what would be cool, let's mix a bottle and a can to make the optimal drink holder"
"well, what do we use?"
"let's use the can top, so it's harder to drink and can't be closed, and the bottom of a bottle, so it won't stand up in a fridge."
"BRILLIANT JIM. YOU GET A PRPMOTION."
