Picture this: You're relaxing after a stressful work day, kicked back in your recliner, adorned in your jammies, waiting for Matlock to start. Suddenly, the entire neighborhood begins to tremble as you hear what sounds like and explosion in your living room. The weird part? There was no explosion and no explanation for the sound or tremors.
