I had one the other day. My kids always tease me about being a blonde. Thankfully they were not in the car at the time. I dropped my DS off at work, and on my way out of the parking lot, saw the sign to the pawn shop. It said, "Watch Batteries installed." I thought, "Wow, why would I want to see that?" Of course half a mile down the road, I had my DUH moment. Go ahead, laugh...
