This is a retooling of the one where Wanda asks Hammie how he got so much sand in his clothes. In fact, most of the strips from this week and last week are retoolings of previous strips.
Does this comic strip take place in the early 90s? Barbara was listening to Milli Vanilli in one strip, Tex mentioned that his favorite singer is Vanilla Ice, and Wayne is using a typewriter instead of a computer.
I’m guessing Tex has a school project where he has to take care of a bag of flour.
