Texas Gov. Rick Perry had another "oops" moment on the campaign trail this morning, forgetting the name of one Cabinet agency he wants to cut, and substituting in another.

ABC News' Arlette Saenz reports that during an interview with WTKS Radio in Savannah, Perry listed the three departments: “Three right off the bat, you know, commerce, interior and energy are three that you think.”

But in that now-infamous debate moment, Perry listed "Commerce, Education, and... Oops." Perry later explained that Energy was the third, and bragged in subsequent appearances that he's since managed to get them straight. Apparently, that's no longer the case.
