Kermit gets a lesson in visual thinking from Harry the Hipster, on Henson’s short-lived Sam and Friends, and what happens when you let it get out of control. Considering that this was filmed in 1959– you really have to admire both the puppeteers and the animators for being way ahead of their time.

A 1966 remake of “Visual Thinking”, with Kermit taking the part of Harry the Hipster, and Grump replacing Kermit as the square.

Though by 1971, both Kermit and Grump have been replaced by Whatnot muppets, and the sketch is more about shapes than visual thinking.
