I think my dad has some Gumby DVD's. I used to watch him when I was little, although now I can't watch Gumby without thinking "I'm GUMBY DAMMIT!"
On a side note, my dad said that back in the 60's he and his buddies would get high and go to this little movie theater in the basement of a record shop and watch Gumby, Laurel and Hardy and the Little Rascals.
