That sneaky ground squirrel which made its way into a couple's holiday photos has become a bit of a web celebrity. He's since been Photoshopped into all sorts of other situations, including Bill Clinton's state visit to North Korea.

However, now you can add the little chap to whatever photos you like, even if you're not an expert in Photoshop. A website called The Squirrelizer has launched that lets you pick a photo online, and put our friend, the ground squirrel, on it.

You can choose how big or small you want the foreground and the background to be, as well as moving the squirrel horizontally and blurring the background. Hit some of the pictures below to see what we came up with, and share your best squirrelizations in the comments.
