Every Tuesday this summer (in July, August and September), in partnership with our friends over at popchips (which is headquartered over on Montgomery and Clay), we'll be testing your local knowledge with SF Pop Culture Pop Quizzes from popchips. Follow and tweet to @popchips and @popchipsSF for your chance to win a...wait for it...month's supply of popchips. Your party-snack shopping for the rest of the summer? Done.

Here's this week's question:

Go! Your popchips await.

Hungry for more? Follow @popchips and @popchipsSF to stay on top what's poppin' in SF, and don't forget to head over to @wholefoodsSF to pick up a bag.
