Perplexing Questions

I fell asleep in the dentist's chair yesterday. The dental hygienist was so gentle and pleasant I slipped into an afternoon snooze. After relating this slightly embarrassing story to WRAL colleague Brian Shrader, he remarked: "Why do dentists always ask you questions after they've filled your mouth full of drills and drainage tubes?"

Good question, Brian! This conversation sparked a discussion of perplexing questions. We have come up with a partial list. Please add to this collection today. Have fun!  Make us laugh on this rainy day!
