For my second cereal-related Christmas commercials post, here's an old standby that aired for several years. I'm pretty sure I was still seeing it on TV when I was well into my teens. Yes, I'm referring to the Fruity Pebbles holiday commercial.
Barney must be even more desperate for Fruity Pebbles than that rabbit is for Trix (I don't understand why. In my opinion, Cocoa Pebbles is the superior cereal of the Pebbles variety). The guy was willing to go out in the snow with no pants or shoes on, for God's sake.
