DRIVING A HYBRID, I only fill up every couple of weeks, and when I filled up last night I was pleasantly surprised to be paying $2.50/gallon, which was much less than I paid last time. I thought it was good news, but it turns out it’s all part of the insidious Big Oil conspiracy to lower prices.

UPDATE: Kathy Grim emails: “You may be really frustrated to know that you should have waited one more day to fill up. I filled up for $2.399 at Callahan and Central Ave Pike this morning.”

Those bastards! I blame Halliburton.
