Bush Hides from the Ravenous Oil Beast of Traal
Someone's been reading "Hitchhiker's Guide to the Galaxy":
Uses for a towel: "wrap it round your head to ward off noxious fumes or avoid the gaze of the Ravenous Bugblatter Beast of Trall (a mind-bogglingly stupid animal, it assumes that if you can't see it, it can't see you--daft as a brush, but very very ravenous)." Maybe he heard it works the same way for gas prices?
