What do you do if your car gets stuck in the mud? Well, get some guy to pull you out with his car. But what if he gets stuck in the mud? Well, you get some other guy to pull both of you out. But what if the third person gets stuck in the mud while trying to rescue the other two cars?

But the Dodge got stuck in the tractor rut
Which eventually pulled out the Ford
