At the end of the episode tonight they did a short bit on an upcoming photo shoot in TV Guide magazine where Mark Harmon shoves a brunette's face into a huge cake. It was apparently unplanned or at least done more enthusiastically than she expected. I think they're on NCIS together. He definitely got her good, figured I'd make it known.
That 2nd picture isn't in the new print issue of TV Guide. The others are. Don't see them on the TV Guide website yet, but it seems to be a week behind the print issue.
