Gas Pump Karaoke

I'm usually an early occupant on the conspiracy wagon, but I actually believe that this wasn't staged. It's LA so it's no surprise that they would find people who happen to be involved in acting. They always seem to do this at the same Costco, so if that's where this couple regularly gets gas, it's not that big a stretch that they would show up twice, and it makes sense that people with acting chops would be more entertaining on camera.
