Kenny vs Spenny is comedic genius. Put two uber-competitive friend (I guess?) together, and watch what happens. Some of the stuff Kenny does to Spenny is pretty twisted, but fun to watch. I love this show. My favorite competitions they did were the "Who's Better With Kids?" and the "Who Can Stay Blindfolded Longest?" contests. The episode in which Kenny locks Spenny in a closet (Boxing challenge) is pretty disturbing though.
Is that show still on Game Show Network, or do they air it elsewhere? I haven't seen it for a while...
