People started drinking PBR in an effort to be original and separate themselves from those "cool" people who drink Corona with a lime wedge in it. Corona is so passe, now the cool kids drink PBR.
I'm quite fond of Miller High Life, but not the other Miller products. While in Grad school, for many years, Friday dinner consisted of $3 pitchers of Miller plus free popcorn, crackers and cheese from a big chunk they put out. Mmmm. The other popular dinner in grad school was chips and salsa. We'd get home from school and be starving. We get out the chips and salsa, to take the edge off. The next thing you knew it, the bag was empty and the salsa gone and we weren't hungry anymore.
Years ago we went on a non-alcoholic beer kick. Both Odouls and Sharps tasted like crap. However we found that PBR NA and Old Milwaukee NA weren't bad at all. They tasted pretty similar to the cheap alcoholic versions
