I pulled a similar joke at my eye doctor. The technician was doing measurements and said: you can blink any time. Me: How about tomorrow at 3 PM? Her: What are you doing tomorrow at 3 PM? Me: Blinking.
It just hit me that if the author named the strip Frank and Earnest (note the additional “a”), it would imply attributes and not just names. Kind of like Oscar Wilde’s “The Importance of being Earnest”.
With the power vested in me (and in my vest), I dub this comic as the best comic of the day!
