A what?

Driving along a local road, I notice a covered wagon in the front yard of a farm.

Mom (me): "Look boys a covered wagon!"

Chandler: "Actually Mom, that's a Conestoga.

Mom: "A what?"

Chandler: "A Conestoga. We learned about wah, wah, wah (Charlie Brown adult voice) wah, wah wah, that is the difference."

Mom: "Wow, that's interesting Chandler."

Just kidding I totally listened to every word he said. I guess I'm not smarter than a 5th grader!
