Jagger: "We need to buy a hybrid car."
Mom: "And who would pay for that?"
Jagger: "Give them our Jeep and tell them you want to trade."
Mom: "Our Jeep is old and has a lot of miles on it. Hybrid cars are worth a lot more money. They wouldn't give us a hybrid car in exchange."
Jagger: "Then give them the Jeep and a new $20 bill! Oh, and pick me up from the bus stop in the hybrid so I can show my friends."
