I remember once I found that in slim 8 oz cans. They weren't like any of the current 8 oz cans that are either shorter or proportional with 12 cans, only smaller. They were about the height of a 12 oz can but slimmer. I brought some to a tailgate and a friend said "Wow, that is the Silver Bullet. Do you drink it with your pinky sticking out?"
I was only a kid and didn't partake, but I remember when Coors (not sure if Coors Light was available) had these ridiculously hard to open push top cans in the late 70s. Apparently they had traditional pull tabs, ones that needed a can piercer, and then the push top.
I heard some people were injured trying to open the push tops. Either with an implement (like a screwdriver) slipping or just cutting a finger on the edge of an opening. I remember when Coors discontinued them in favor of modern push tops with the captive tab opener, they had a commercial that was ridiculing their old design and how hard it was to open.
