That's because you're looking at the unscripted input of the users themselves. It's been long enough since we've seen any such. Everything on TV is scripted, even the "reality" shows.
Except now, with the writers on strike, they got no more scripts. Cry me a river while I bring up YouTube again....
I like Jeopardy. Even Wheel of Fortune is better paced than some of the other shows.
And I actually have to preview some of the stuff on the Game Show Network. My son turned off the set during a rerun of Greed or The Weakest Link or something. I turned it back on during an episode of Dog Eat Dog (or something like that) at this very moment -- a girl was throwing darts in her underwear (at first, I was hoping it was a bathing suit, at least). The host told her that if she wanted to throw one more dart, she only needed to score 10 points. The woman replied, "Okay, my bra." At which point, she took off her bra in front of a studio audience (and two male contestants just a few feet away), who got a great gander before she covered herself with one arm.
She then threw the dart, scored the points needed and jumped up with both arms raised in the air. Classy stuff. But, hey, it's all pixelated, so it's good tv, right? I shut it off. I've since been told that that segment of the show is called "Strip Darts". Times have changed.
