I stumbled across this site today, and can't believe I've never heard of it before.
Democratic Underground is a fever swamp of far-left delusional thinking and I'll occasionally visit just to get a chuckle over the bizarre drivel that gets thrown around by the DUmmies (as they're known by right-wing bloggers) over there. The problem is I often feel like I need a long, hot shower with disinfectant afterward.
Well, no more. DUmmie FUnnies gathers some of the more crazed babble and reposts it with a humorous running commentary. Check it out.
