March 15, 1951: Charlie Brown's youth-preserving regimen

Another turnabout joke, that being my name for these strips where there's a sudden rush of anger in the last panel based on something a character said, flipping the mood instantly from casual conversation to rage.

The cause here is another insult to Patty, resulting in another exclamation point, and another comment from Charlie Brown during the following chase. The joke here is actually rather funny.
