Photo Taking Application with Jokes
Uff, there are a “lot” of photo + fun applications in the App Store. Here’s a few I’ve tried:


Face Substitution
Swap Faces: Very funny (has a Lite version)
Face It: Allows you to add overlays of things (glasses, mustaches, etc)
Face Melter: allows you to deform a face (it makes you laugh a lot to be honest)


I have performed a “Face” search in the AppStore for iPhone apps and there are quite a lot, I suggest you take a look at those.
