I have found the reason for the wonderful drop in the price of a gallon of gas!

"Since July this year, crude oil prices have fallen from $147 to $64 a barrel. Similarly, average gasoline prices have fallen from over $4 to a national average of $2.69 a gallon. When crude oil and gasoline were reaching their historical highs, Congress and other wackoeconomists blamed it on greedy oil company CEOs in their lust for obscene profits. But what explains today's lower prices? The only answer, consistent with wackonomic theory, is easy: Oil company CEOs have lost their lust for obscene profits. Or, maybe, since many of these CEOs are getting up in years, they might have begun to heed Matthew's warning (19:24), "It is easier for a camel to go through the eye of a needle than for a rich man to enter into the kingdom of God."
