Dispatch from the Department of Glass Houses . . .

The Good Morning America crew had a bunch of yucks today at the expense of the Sparks, NV streets department employee who spelled "scool" on the asphalt. But within minutes, two ABCers made math mistakes of their own, one of a political sort, the other climate-related.

RON CLAIBORNE: In Sparks, Nevada, someone in the streets department could use a spelling lesson. A sign painted on the street announces a nearby facility is a "s-c-o-o-l" [sound of Claiborne chuckle]. The city plans to fix the sign as soon as possible. That's a first look at the headlines, back to Bill and Kate. Everybody knows school is spelled with a "k."

Great guffaws ensue.
