Until I turned about 10, I thought "carpool" was another word for El Caminos -- the cars that look like they're half pickup truck. I always wondered why I had never seen one put to proper use, filled with water and people in swimsuits. To this day, I want to try that version of carpooling!

- When I was a kid I used to think the "carpool lane" was an actual pool cars went swimming in— skeez
- Some sport cars have a double exhaust. I wondered why. Why would people want to pollute twice as much?— F*ck the environment?
- I thought that people were like cars because cars have exhaust pipes, and people fart.— Matt
- I used to believe that "carpooling" meant you were outside the car and pushing/pulling it to your destination.Anon
- I wanted to grow up and be a truck. Not a truck driver, a truck. Anon
