One time I was a pax on a SWA flight from CMH to MCI, and this dumb chick in front of me was talking to her fellow passenger about how stupid it was that the Kansas City airport was actually in Missouri...most people know that Kansas City proper is in Missouri, not Kansas.

Also I was once on an Air India 74 from ORD to LHR, and this chick from rural Tennessee beside me who had never flown before literally starting crying out loud and saying she wanted to get off the plane after an APU malfunction caused the lights to flicker. I was trying not to laugh.
