Billy: Are you ready for the camping trip?

Jennifer: All set. I've got my makeup, my CDs, and my portable TV set...

Billy: Hellooo! We're supposed to be getting back to nature.

Jennifer: Yeah, yeah. Anyway...I'm packed. Are you?

Billy: I've been packed for a week. All my stuff is in this backpack.

Jennifer: Let me see...two books...birdseed?

Billy: That's trail mix!

Jennifer: Same difference. What's this?
