Last week The Boy spiked a fever one day (which subsided quickly), then woke up with headaches for the next two days. We gave him some kids' Tylenol and a small piece of chocolate -- small piece! -- for the caffeine boost. Then we tried to explain the caffeine/Tylenol combination.

Us: The caffeine in the chocolate will help make the Tylenol work faster. It takes a while to work because it has to travel through your body before it starts working on your headache.

The Boy: All the way through my body and through my penis?

I think a few lessons in how the digestive system works, with an addendum on medication absorption, is in order.
