Okay, so this was a good one today. We're in the checkout line at Wegmans (grocery store) and DS6 says "Dad! They use the binary system here!"

"What? Where?"


"I don't see it."

"See, the checkouts. The light [in the isle] on means that it's open. When the light is off, they are closed! It's binary!"

"Uhh... yeah, you're right!"
