Probably intentionaly filmed, "discovered", and "revealed" JUST for this purpose... no doubt this clip will be passed around the net a billion times -- free McDonalds publicity yet again.

There was supposedly (late 70's) an ad that was geared towards dieters that said if you placed your nose in a bag of Frito's for a few seconds, your hunger would be alleviated. Of course, sales shot up as thousands bought Fritos to try it. Think the diet trick worked? Give a dieter an open bag of Fritos and see.

Also, subliminal messages go far beyond the flashbit shown in the video clip here. Bikinis in beer ads, white coats and stethoscopes in drug commercials, big bands and flags waving in Army recruiting ads, super close-up shots of glistening hot cheeseburgers on an open broiler... all meant to provoke an unspoken response...

Well, gotta run... craving a Big Mac now for some strange reason!
