Dr. No
From Muppet Wiki
Dr. No is an eye specialist who is visited by James Bond, who has been sent to the doctor for problems with reading. Dr. No tests his eyesight with a sign that says "NO" on it, but can't get James Bond to read it properly until he removes his glasses.
The character is a take-off on the title character in the 1962 film Dr. No, which inaugurated the James Bond movie series.
