Ironically, it's the one I watch (tho not this year because I made a New Years Resolution to give up reality TV) -- American Idol.
The other two, I can merely cringe in emberassment (over either the fact that I'm actually watching it, or over the skills, or lack thereof, of some of the contestants), but I can handle clumsy dancing and skating more than I can handle PEOPLE WHO CANNOT SING COMPLETELY TRASHING A SONG THAT I REALLY LIKE, OR ONE I HATE TO BEGIN WITH (and I'm not sure which is worse.) And it seems every season they have to have at least 2 in the final 12 finalists who should have been tossed LONG before they got to that stage, and at least one of them has to stay in for WEEKS AND WEEKS AND WEEKS before the audience is finally put out of their misery.
