i have a 16 month old at home, and she loves to watch a show called Bunnytown on Playhouse Disney. I actually like it, the show is made by some people who used to work on the Muppets, so it is a pretty funny show.
however, there are a few songs they sing, and I can honestly say they are in my head, and my wife's head non-stop.
Let's go everyone, we're gonna go down to a cooky little placed called....BUNNYTOWN!
I could do the rest, but you get the point.
