The risk with fake data is that Google is clamping down on dubious rich snippet info which could harm you in the long term.

I did experiment with some wacky photos though (including one which was a Facebook like button) to see what would happen with it. Google didn't notice, of course, but that doesn't mean the risk is zero.
