Yesterday, for the first time ever, $40 failed to fill my gas tank

May 2004: Regional gas prices top $2 per gallon -- "Jeez, this is inconvenient. I can barely fill my tank with Andrew Jackson's trading card. I feel like punching the passenger seat."

January 2006: Regional gas prices top $3 per gallon -- "Wow, suddenly this photo is more quaint than funny. I'm spending more money on gas than on some nights out in New York City. I feel like punching oil company execs in the face."

May 2008: Regional gas prices top $4 per gallon -- "[Expletive]! [Expletive]! [Expletive]! [Expletive]! [Expletive]! I feel like a [expletive gerund] punching bag."

So yeah, I'm a little punchy.
