HELP! I am trying to figure out what the name of an old children's educational video I used to have. All I can remember is that it was puppets and about letters and numbers. I remember very vague things like a guy getting angry, or upset all the time. A guy driving a delivery truck, sheep counting, and a scientist putting strange things into test pots. I know this is very vague but any info would be awesome. Also, it wasn't Muppets or Sesame Street. Thanks!

It's called "The Letter People." It's a great curriculum that's still used today, just a little more modern.
