April Fool's?

We didn't do anything for April Fool's Day this year (if I'd thought about it then, we'd have had breakfast for dinner as a sort-of celebration, but we didn't), so the day passed with only the usual fake pregnancy/engagement announcements on Facebook. 

But then, I was loading pictures on to my computer later and noticed that there were a few on there that I didn't take. I included all of them for your enjoyment... perhaps this was Carson's idea of a good joke.

The last one is my favorite.
