1. Milwaukee Special Reserve Ice (couldn't even finish a can, and I've drank some serious garbage in my time)
2. Steel Reserve
3. Budweiser American Ale (closest thing to piss I've ever had)
Here's a fun rule of thumb. All beers start with five points. Deduct a point for each of the following words "Special", "Milwaukee", "Ice", "Reserve", "Best". You then have a fairly useful scale at which Milwaukee's Special Reserve Ice" serves as a baseline for awful beer.
I actually have a bizarre fondness for Red Dog. It's like the White Castle of beers (and I love White Castle). When I first lived in a house with roommates, they would drink my beer. So I started buying Red Dog, which carries a trashy stigma, but to me is no worse than your Hamms or Schmidts or PBRs of the world. I came to be associated with Red Dog. I would offer it to people at parties as a joke, saying, "Bite of the dog?" And they would almost always decline.
I don't drink it much anymore, but every year for a long time I have thrown a super bowl party, and I always have a case of the dog on hand. My friends drink it at the party because it's become a nostalgic thing due to my association with the beer of the years.
Good times.
