I asked Kurt if he was teaching Harper to siphon gas. He said, "Well, you gotta teach them young to be prepared for the zombie apocalypse." True.
Two additional things:
1) If you are watching The Walking Dead, you'll know Carol would approve.
2) Kurt blew into one end of this hose like a trumpet and the sound came out near Harper and she looked a bit spooked and very nervous. It was kinda funny.
