This show has been on even BEFORE I was born... And there have been some changes to it. For example, the human host used to be a man named Steve, but the people at Nick Jr. said that "Steve had to go onto college", thus bringing Joe to host the show. Also, I had a Blue's Clues set of sheets and a comforter when I was three. It was a BIG HIT with me. I love, Love, LOVED it!!!!
