Cookie Monster's Sad Demise

Covered in crumbs, Cookie Monster visited the doctor for help. "What's got you down, Cookie Monster," the doctor asked.

Cookie's pupils bobbled and rattled with existential angst. "When me eat cookies, me feel bad." The doctor ran some blood tests. Cookie waited for the results. The doctor returned, grimacing.

"Bad news, Cookie."

"Me sick?"

"Diabetes."
