Does anyone remember this classic SS moment from either the early 70's or late 80's? Gordon approached the steps of 123 Sesame Street and he discovered a huge purple E on the steps and a wire was sticking out in the back. The wire was also attached to a fuse box controlled by Biff and Sully. Biff explained to Gordon that they were going to show the kids the difference between an E and an F. Then Biff told Sully to fire away. And Sully activated the box and the bottom part of the E blew off turning it into an F. Then Biff told everyone an F is just an E without a bottom leg.
