Do you know the name of a show that was about a brain in a glass sphere that was at a circus? A man kept coming to visit the brain in the sphere. The man became friends with the brain.

The brain asked the man for the favor of letting it inhabit the body of the man for just a day, so it would be allowed to experience senses again. The man agreed to allow the brain to inhabit his body and allow his brain to go into the sphere for the day, to give the brain his 1-day wish.

After the man and the brain exchanged places, the brain laughed at the stupidity of the man. The brain said he never planned to return to the sphere, and the brain left the man in the sphere forever.
