Uncanny Valley runs too deep with these puppets. There's a puppet they somehow lump in with the kid puppets that's an ugly bald man with narrow eyes (possibly crow's feet) and a huge, elderly person nose. And they didn't even attempt caricature like Spitting Image (or the Krofft Brother's DC Follies thing that was the US equivalent), and they aren't stylized enough like the Gelflings in Dark Crystal. They come off just, really...really ugly. And I agree... those big clumsy fat bodies and awkward arms... they might as well use socks. Probably look better.
I did a YTP of them some time back... I cannot stand to watch any more of it. Now I know why, ironically, there are so few YTP's that use them other than Ersatz Ernie's M song. Just piling through these segments in order to find funny stuff to be taken out of context is grueling! I'm only sort of happy with the end result (I liked my Letter People one better... at least that's a far more pleasant show), mainly because I just wanted it done and I couldn't find any real humor in any of the skits because they were THAT bad.
