Someone is in for an ass whooping when he gets home.

LENOX, Pa. (ABC News) — No Obama bus tour would be complete without a stop for the president’s favorite treat: pie.

On the road to Scranton this afternoon, the president made a surprise visit to Bingham’s Restaurant in Lenox, Pa.

“Hello, everybody,” Obama exclaimed as he walked into the sunny restaurant with Sen. Bob Casey by his side. “I hear you’ve got the best pie… That’s the word on the street.”

The president walked straight up to the counter, where more than a dozen pies and sweet treats were on display under a sign that read “Try The Pie.”

A tempting coconut cream pie was already set out. The owner later told reporters he had heard it was one of the president’s favorites.

“Coconut cream pie,” Obama said with excitement.
