I’d rather not. Besides, I don’t think those are pimples. Looks like something else. Leprosy. Carbuncles. The dreaded Leprobuncles.

Let’s go to the illustrations:

Pimples seem to be the least of Spotty Dave’s problem; he has a strange Irish Zombie look going on. At least he realizes that he’s disfigured and unattractive, and hence unsuitable for the silver screen. We now switch to Grannie’s kitchen:

Yeast? Apparently.

Frannie speaks in a peculiar mix of Shirley-Templese and unpunctuated hack copy; someone give that kid a box of periods for Christmas. Gran’s just plain folks, though. Land sakes! Always trust medical advice from someone who says LAND SAKES and went directly to shapeless grey matronhood at the age of 40. Especially if she's making pies.

Florrie knows it was Grannie, but is content to soak up the credit. Note how the Best Girl can’t spell Fleischmann’s. Makes her sound drunk.

And how does it work? Why, it clears skin irritants out of the blood. It's a regular blood-scrubber, that yeast. Everyone knows that.
