Nobody

As Brody enters the driveway he realizes that the person that he saw standing in the driveway wasn't a person at all, but just a cardboard cutout that his dad was using as a part of his job in advertising.

Brody gets out of his car and puts the cardboard cutout in the garage.

He goes inside the house. Seeing that he's going have the house to himself this evening and it's pretty hot inside, Brody strips down to his underwear.

He grabs a snack and plops himself down in front of the tv.
