Just a Face and a Caption: Conviction By Counterfactual Clue

I understand that the pregnant-mule thing is mentioned in the trope description, but an image of a baby mule by itself has nothing to do with the trope. Donald Sobol, who apparently used it once, is mentioned in the caption and in the examples, but that's it.

That said, I have no idea how to pic this.

I don't have any idea how to pic this either, and since it's sat idle for so long. I'd say we can leave it for now.
