The downside, beofre they changed their caps about 15 years ago, is that you had a pull tab type removal system for Mickey’s. And 80% of the time, it lead to spillage on your clothes.
Actually, I was okay with the pull tabs. There was a technique to it as I recall, and once you mastered it, spillage only became an issue after Mickey’s #7 or #8 when the C2H5OH really kicked in. I lived in Ohio back then, when they still had 3.2 beer (Godawful stuff, for the uninitiated) and Mickey’s had the multiple virtues of being a full alcohol brand, extremely cheap, and better-tasting than most other low-price entries in the Cheap Beer for Penniless Graduate Students sweepstakes.
