#7: The Dog Finally Found His Ball
This billboard pairing turns two separate ads into one cute little scene. The bulldog on the top sign looks like he is staring down at the tennis ball on the smaller billboard below. Neither one needs a complicated slogan because the placement does most of the work.

There is something very funny about making a dog billboard interact with a completely different sign. It feels like the pup has been waiting up there all day, hoping someone will throw the ball. A basic ad setup suddenly becomes a tiny roadside cartoon, and that makes it memorable.
