That last panel even works by itself.

Reminds me of a TV ad, older than this comic, for a frosted cereal (probably not the first one that comes to mind) and the adult about to consume them has the inner dialogue “What about fat?!” “Wimp!”

(I always heard it as “Wamp!”, so to this day I’m not completely sure if it was an early example of a spoken sad trombone, but “Wimp!” is more likely.)

They don’t make ads like that any more.
