Since he's a bird, isn't this technically singing and not whistling?

I guess putting a dog in charge of audio equipment was not the best of ideas.

When I was a kid, like four or five, I had one of those amazing brown Fisher-Price cassette tape recorders, and they came with these books that were basically various shots from Charlie Brown specials with narration on tape. What I did was trace the books onto paper, and then play the tapes on a VHS recorder we had, making some little videos. I had these tapes up until a few years ago, but they had disintegrated so badly that I couldn't transfer them to mpg format. This was one of those specials.
