This week I got a trivia question from a reader named Len Maurer from St. Louis MO.

Len writes, "On Charles in Charge what was the last name of Scott Baio's character, Charles?"

I actually get this question quite often, and the answer is he didn't have one. Now some of you may insist that he did have a last name that was never mentioned on the show. However, according to a conversation I once had with Al Burton, executive producer of C in C, Charles was never given a last name ... ever.

Thanks for the question Len.

Now for this week's stumper...

In honor of Dave Letterman's multiple Emmy noms, this week's question is about Dave.

Before David Letterman was as recognizable as he is today, he would bother people on the streets of New York as a character named what?

Good luck.

Well done, Pahles. He was indeed called Mr. Curious.
