Ever had this happen? (pics)

A rifle went off under my car.
Nah.
I went out to start the Dodge in the driveway.
Turn over.
Paused.
Pump the peddle once or twice.
Turn over again.
BAM.
Sounded just like someone had let go a 30 06 behind me.
The neighbor down the street came out an started looking in the woods.
I drove down and told him what had happened. LOL
Guess I'm getting close to springing for that TTI system.
