Do you kids have a show that completely mesmerizes them?

Our daughter was never big on TV when she was young, but we started letting her watch more as she got a little older. She's now almost two, and most shows she doesn't care at all about. But there are a few that she loves to see and could sit down and watch an entire episode. She is absolutely hypnotized by Yo Gabba Gabba, Dora, The Wiggles, and sometimes Sid the Science Kid. DO your kids have any favorites?
