And hydrogen is not an energy SOURCE, it's an energy storage MEDIUM. You have to MAKE it. GAHHHHH!
That's fistful's fault.
McCain saw him putting a garden hose in the water tank input of the Straight Talk Express, and came over to talk with him. Fistful started talking all sorts of nonsense about unicorns, kindness, the golden rule and cars running on water... then asked him to apologize to his mule!
"Mule? What mule?" McCain glanced around worriedly. "We don't allow their kind around here."
Fistful patted him on the shoulder and praised him for being a good "alternative" to Obama, and handed him the water-hose as he walked off, shaking his head.
To this day, McCain thinks he was in a gas station.
