From the youtube description:

"An 87-year old with an appetite for adventure joyrides through a football field on a souped-up, high-speed mobility scooter. And he's got something even wilder up his old-man sleeve for Game Day."

On a positive note, this effort from Deutsch doesn't feel like a Taco Bell spot. It was shot beautifully and the legal line "Do not do this," is pretty funny.

On the other hand, I can't exactly say why i'm not enamored with this. Is it because it's for Taco Bell? Is it because I have seen the ageist "old person acts young," a lot? Is it because Grandpa seems like a dick? Is it because the title "Grandpa goes wild," seems like a very obvious attempt to make something go viral? is it because there's already a "grandpa gone wild," video that is, well, a bit different? Is it because very few teaser campaigns ever live up to their reveal?

Is it all of the above? I don't know.

Either way, it's going in the meh pile.
