This member said they went to school with Brian Henson. It was Bring Your Parent to School Day, or maybe parent/teacher conferences were done differently, I don't remember exactly. The member and Brian Henson had a Korean chemistry teacher who was doing some wacky experiment to show off for the parents. But no one was watching the teacher. Everyone was watching Jim Henson watch the teacher.
The next week Dr. Bunson Honeydew made his debut on the Muppet Show.
I don't know if that is a true story, but as the line from Smoke says "It's a good story, Auggie."
