I ran into a fella in Best Buy a couple months ago who was complaining to an employee in the DVD section about WS movies and how they're inferior to 4:3 and pan&scan because you're losing the top & bottom of the picture. She (the employee) was trying to explain the benefits of WS, especially 16X9, but he wouldn't have any of it. The guy asked me which I preferred so I defended the employee's statements and went further to help explain more of the finer points of 16X9. But to no avail. This continued for about 15 minutes or so.
I finally got tired of listening to him bellyache about it so I asked him if he had a dollar bill, and if so, may I see it. After a few seconds of mental calculations (and a raised eyebrow from the employee), he opened his wallet and handed me a dollar bill.
I held it up so he could see the whole dollar and said "Widescreen". Then I carefully folded it into thirds and ripped off the two outside sections. (At this point, there was a sharp intake of breath from J6P and a slight giggle of delight from the employee.) I handed it back to him and said, "4:3". Then I handed him the two pieces I tore off and said, "Move them around for pan & scan".
The employee dropped the DVDs she was holding because she was laughing so hard at that slack-jawed little rat just looking at me with his mouth hanging wide open.
I don't know if he ever got the point of the lesson, but it cost him a dollar nonetheless.
