I once brought a beer called Grolsch.

It was a bottle one not a can. It had no cap to pop off and it didn't twist. ¬_¬ ...For the love of god I couldn't figure out how to open this bloody beer. I gave it to my brother and it took him ten minutes and he tried to smash it open. ¬_¬ He gave it to my Mom, whom just opened it with ease. -_-
