JOEL: We ask him his favorite song every five minutes, and he's somehow able to always list the current top single on iTunes at that EXACT moment.
TESTER: What about now? GREG: "Fireflies" by Owl City... no, wait, NO... actually it's "Replay" by Iyaz.
BART: FAScinating... GREG: Wait, NOW it's the Glee cast version of "Alone". NO... "Take a Bow"! NO!! "ALONE"!!!
