I recently found this on YouTube:
"I was watching the end of today's (1/21/07) Iron Chef and noticed the screen quickly blink red. A few seconds later I start thinking, "Was that the McDonalds logo...?" Thanks to the magic of my Dish Network DVR, I rewind, and put it in to slow motion.
Sure enough, Food Network is allowing McDonalds to run subliminal advertisements in the middle of their programming!"
