Opposites Attract??

This is actually an old pic I just found in my archives.

Is this a case of His and Hers? A case of 1 Hummer + 1 Smart Car is equivalent to 2 Normal Family Vehicles?

I thought that if a Smart Car and a Hummer parked in the same driveway, they would trigger some law of physics that automatically converts them both into anti-matter.

They are so totally pretending not to know one another.
