So I was on the shuttle from New York this morning when who shows up next to me but Reverend Al (it's been a good week for shuttle-spotting: Placido Domingo! Dan Bartlett! Mark Leibovich! A guy who looked almost exactly like Joe Torre!). Sharpton, who I think was coming down to D.C. to yell at President Obama about something, was looking as thin and dapper as the last time I saw him two years ago.

"What's your diet secret?" I asked him. After all, stripping weight away is somewhat easy, compared to keeping it off. Sharpton put his arm around my shoulder and said, "I'll tell you the secret. You ready for the secret?" He lowered his voice. "Never, ever eat anything after 6 p.m. Never."

It's at least as good as any other advice I've ever heard.
