Jessica: I'm sorry, Bart. You know my parents can't find out about us.

Jessica: Hey, you want to go skateboarding?
Bart: Actually, I was hoping I could sit down for just a second.
Jessica: [cajoling] Come on! It'll be fun.
[looks around, then kisses Bart]
Bart: Wow! [stands up] Now I have the energy to do anything!
[doubles over again] Just give me two minutes.
