OK. Let's leave it at this. There are hidden passageways in everybody's fuel
tank. Never seal your tank or your hidden passageways will get blocked and
you'll run out of gas with your fuel gauge showing 3/8 of a tank full. I'm
going back through the mirror now. They're waiting for me at the wedding.
