I don't know; there must be an audience for a plot-less prank call show with the plots acted out by puppets with stereotypical acting and clichebackgrounds- I just don't find it funny. At all.
Back in the day here in Canada, when South park used to come on Comedy Channel this would come on soon after, and I honestly tried to watch it a few times when I was a kid, while I was supposed to be in bed, staying up late to watch the grown up shows. I don't know I must have been 12 or 14 or something and I found it annoying, even then.
I find it all but unbearable now. I've never liked Jimmy Kimmel. Not on The man Show not as a night show host and definitely not his production work on this. Look at the names they get for this - Wanda Sykes, Adam Carolla, etc, so, obviously for the cheap recording of the phone calls and the fairly cheap puppet enactment, a major budget is spent on the show's poor script writing and post-production which, for me, I can't imagine how much, but I'm sure whatever the budget for this low-grade entertainment, too much. Combine that with eating up valuable air time and I have a very hard time justifying this show being on at all. I'm sure this is an easy way to inflate Jimmy Kimmel's already substantial paycheck and a way for him to keep some of his cronies who he came up with relevant, other than that I have no idea why this is back on the air.
