A centaur is inside a store. He is purchasing some things from a clerk.
Centaurs don't exist, and they probably wouldn't be allowed in stores if they did.
What is he buying?
Looks like you're already familiar with the side effects.

The side effect of this man's prescription drug is that it turns him into a centaur. This funny part is how nonchalant the pharmacist is about this side effect: her response is as if she sees this very unusual side effect quite regularly, and it's not a big deal. Apparently, the only action required is to be familiar with the side effect, as if it were a more benign one like drowsiness.
