Had DUDE beer a couple times last summer, as my brother and I got bored and started trying every type of cheap beer. I didn't like it much, but have to say the worst beer I've ever had is AGD (Alberta Genuine Draft)...yuck. We got on a kick near the end of my vacation where we started drinking Black Label Supreme (8%)...now that was good cheap beer! Whoever mentioned Black Label before, it is the king of the cheap beers in my opinion too.
Oh yea, had Bud Light Lime last week, and it tastes more like a cooler than a beer. It didn't taste bad, but you can get the same effect by adding some lime juice to a beer if you want...
