Professor Popinjay's Compendium of Perspicacity

Matthew Boyd asks:
Professor Popinjay,
Does Cookie Monster ever get a headache from the way his eyes jiggle or is there a gyroscope in his brain that compensates for the eye movement?

Dear Matt:
—–Cookie Monster (or Sid as he is known to his family members) seems to suffer from a hereditary condition known as Nystagmus, the symptoms of which include rapid involuntary eye movement resulting in reduced vision and coordination. This might explain why, despite his addiction to cookies, he often eats things which are cookie only in shape and appearance such as the rice cakes painted to look like cookies he so often finds on the set of Sesame Street.
—–As to the inner mechanisms of his brain, research shows that Sid’s interior consists solely of Frank Oz’s hand most of the time. As Frank Oz is in essence Cookie Monster’s brain, the question arises, how does Cookie Monster see at all when his jiggly eye-balls don’t even function as eyes and are in no way even connected to Frank Oz’s actual brain? The answer is a small monitor beneath the puppet stage with a video feed that enables Frank to see what Cookie Monster is doing in a reversed mirror image.
—–I realize this rather forensic assessment of Cookie Monster’s anatomy is disillusioning especially when you consider all the other things Frank Oz might do with that hand. So as to not completely ruin your childhood I shall leave you with this happy quote from the “monster” himself:

—–“No cry because cookie is finished. Smile because cookie happened.”

I hope that answers your question!
Sincerely, Professor Popinjay
