Lewis and Clark
It took me years to realize that Lewis and Clark were separate people from Lois Lane and Clark Kent. Let me justify this past silliness of mine: first, the show Lois and Clark starring Terri Hatcher and Dean Kane was on around the time I began to hear mention of Lewis and Clark. Second, my mom’s name is Lois, but people would for some reason err and call her Lewis, so I thought that was a common mispronunciation. I was fortunate enough to have never said anything about my ignorance publicly until now. Oh, whoops.
