The Ford Explorer Equinox

When three Ford Explorers of the same engine size align in a formation, they will cause an nuclear explosion and take out an entire city block and poison the rest of the city.

Ford Dealerships never place more then three Explorers next to each other for fear that The Ford Explorer Equinox will trigger and destroy the dealership.

Steve no longer wanted to live his life so he tried to preform the Ford Explorer Equinox, but the other ford drivers were not having any of that.
