"Come on, get happy!"

This is one of the weirder contrasts between a book's title and its cover photo.

I guess that even when you're marked for terror, there's still always a reason to get happy. Or as my friend Donna said, "Maybe that's the photo the terrorist was using for a dartboard."

So that would be a case of "Come on! Get 'Happy'!"

Note: None of these jokes make any sense unless you've seen the Partridge Family TV show. (Via.)
