Best line of the day, so far

“Instead of sunblock, they’re recommending A-1 Sauce, it’s that hot.”

David Letterman on the California heat wave (116º in the San Fernando Valley).

Another good one from Letterman:

“He’s inspired a new line of clothing, and I believe if you want some of the John McCain stuff, you can go to — it’s being sold at, oh, at the Very Old Navy.”
