I'd be a responsible adult and invest it.... PFFFFTTT... yeah I'd blow it all on enamel pins, shiny rocks, comic books, and video games.
Orrr, I could take that trip down to Pigeon Forge. 1000$ would buy a Pirates dinner theater, day at Dollywood, and lots of cheesy attractions. (Not spoken with disdain, cheesy is my favorite flavor of attraction.)
