And yet, “33” is somehow a sacred number to many Pennsylvania college students!
For some reason, Rolling Rock beer, brewed in Pennsylvania, uses the number 33. I don't think it's related to the notorious 33 beer from Vietnam. During the Vietnam War, it was said that the beer contained formaldehyde to keep it from spoiling in the tropical heat. It is still brewed, and I have had some myself, and I'm still here.
Here's a famous tribute to that beer.
