This show is awesome. I enjoyed it since I was 11. It had a lot of unintentional references (e.g. Hey look! It's The Cat In The Hat!)
Zaboomafoo's references are just a coincidence, which they are not intentional. I even heard Chris and Martin say "Zaboo" at different speeds. Chris was saying "Zaboo Zaboo Zaboo..." in a high pitched sped up voice. Martin was saying "Zaaaaabooooo!" in a deep slowed voice. There's even one episode when Chris, Martin, and the titular lemur go to a school with some kids. Zaboomafoo was using a computer. He listened to his own voice and Martin's voice on the Zaboomafoo website. I love this show, even when I grew out of TV, I still love this show. I give this show a 5.0-star rating because it's a childhood favorite.
