It's one of those fads.. plain ,and simple.. granted some of the watchers might "actually" like it,but 90% like it because they want to fit in.. personally,I don't care how uncool I become.. rainbows,and ponies are not for me..
I really don't get why people are obsessed with it. People usually claim the humor is "subtly lined with adult oriented jokes" but I just don't see it. I mean I can't hate the show anymore than I can hate Blue's Clues- its a kid's show and I'm not the target audience.But hey, whatever floats your boat right?
