This topic dredges up memories of college parties, kegs, and getting the most beer for our meager bucks. And I only graduated 4 years ago.
Natural "Natty" Ice and Natty Light top the list. I think a case ran us about $9. When we wanted a "better" beer, we would get.... Keystone Light or Keystone Ice. $11/case. There was one day one of my roommates bought a case of Schlitz... $6/case. The list goes on and includes names such as Milwakee's Best, and Lionshead. With the exception of Keystone, I got sick from everyone of those beers, and it wasn't just the low tolerance. I won't even go into the 40s we would on occasion.
Thank god I discovered better beers and someone bought Yuengling one night. I still don't mind the occasional bud or miller, though, but mention Natty and I cringe.
Oh and I forgot one! MGD 64. Tastes like piss water.
