I wasn't even watching TV, I was just in the house for a moment while I was taking off the snow tires and putting on my very well worn Goodyears.(very shabby on the outside shoulder to boot!)
Any how its an animated commercial in the style of Pixar. It shows an M&M candy sitting on a park bench. He's staring at a squirrel who is starring back at him. Suddenly there are many many more squirrels...and a narrator says...
Every M&M candy should not forget, there could be a Peanut in side. The last scene of this very short comercial is a Squirrel LUNGING at the M&M. GRUESOME! I loved it!
