The Battle of Downingtown?

Madison.

It's not often that one's hometown gets mocked on NPR, so I find it well worth pointing out. Even if it did occur on Wait Wait, Don't Tell Me! nearly four years ago. "Bluff The Listener," specifically. Adam Felber does mispronounce Downingtown as Downington, but he's far from the first. A lot of people seem to have trouble seeing that w at the end.

In case you're wondering where this misguided blip off the Pennsylvania Turnpike is, here's a map. If you're into bogus history, it sounds like Downingtown's the place to be.
