I am horribly, terribly scared of clowns (and people dressed up in costumes or masks that obscure their faces, for that matter), but even I find this contest on Worth 1000 interesting. The contest lets people with wicked Photoshop skills put their techniques to the test with regular challenges. This one is to give the celebrity of their choice a Ringling-style makeover.
The one here is by Worth1000 submitter SassyDeb, and in case the grease paint threw you, it's Hugh Laurie from House.
Here's the whole gallery, but you can also find previous incarnations of this particular challenge here.
