He must be given props (literally) for going above and beyond to embody Kim Kardashian during Fallon's game of First Impressions. Like, much better props than a box of tissues, but it was enough for Jimmy to cop who it was. That or a producer told Jimmy the answer to progress the segment because no one was ever going to get it. EVER. 

The biggest laugh of the night went to Fallon's impression of Mike Tyson, because that's always funny. 

In case you're wondering where Josh's pornstache went to, Jimmy shaved it off earlier in the show.
