Oh this is sooo funny! I stumbled across this celebrity look alike collage creator and just had to give it a go myself:
That's so hilarious - especially the Calista Flockhart bit - I reckon I could fit 10 of her inside my jacket! LMAO!! There was one more that I left off, but was the most hilarious if not the most embarrassing one - JET LI!!! Hahaaaaaaaaaa!
You've gotta try it yourself! Leave a comment here when you've posted it on your blog, and I'll come and have a look! :)
