Mitt Romney has been accused of a lot of things, but having a sense of humor isn’t really one of them.

(Polling indicates that people find him stiff and robotic.)

So, you can imagine why he’s been working pretty hard to seem like a fun-loving jokester lately, hence his recent appearance on the Tonight Show with Jay Leno.

But, on Sunday, which was April 1 (for those of you without calendars), Mitt wasn’t in on the gag. It seem that his staff, along with Congressman Paul Ryan and Sen. Ron Johnson, played a prank on the Republican presidential candidate. 

The joke went like this:

Paul and Ron were tagging along with Mitt to a campaign rally in a ballroom. Mitt’s staff had managed to get him there without seeing the crowd. When he walked out on stage, there was just a small group of staffers to greet him in an empty ballroom. (We’re going to guess someone yelled out: “April Fools!”)

You know that’s actually a pretty good prank to pull off with all the stress and business of the campaign trail.

We might have gone with something a little more edgy like a fake paternity suit or an Anthony Weiner-like online pic scandal, but we also tend to go too far in our practical joking and aren't allowed to pull pranks in the office anymore.

(Come on, KAC!  We told you the gun was loaded with blanks!)
