I miss this show!
I loved this show so much when I was 8,9 years old. I've always loved animals and animal humor and this show used to be on Nick at Nite in the late 80's and I watched it every night and laughed so obnoxiously! Around the same age I also worked at a barn down my street and taught myself how to ride horses (bareback- I was quite fearless during that golden age BEFORE I had broken any bones!) and I would always sing the song. My favorite horse at the barn was this really good natured black thoroughbred and he would let me move his mouth like he was talking, I'd move his lips and say "Wilbur!!". Um, my friends thought I was crazy! The show was just so cool for kids though, I know when I was 9 years old, watching Mister Ed would put me in the best mood.
Something that kind of reminds me of Mister Ed are those "Carl" books of that rottweiler that hangs out with the baby and they go everywhere together. Those books are so cool!
