If there's one thing Jimmy Kimmel is great at, it's getting a bunch of famous people together to make fun of themselves. It's become an annual tradition for the late night host to follow up the Oscars with a star-studded spoof that basically lets a bunch of A-Listers not take themselves too seriously after taking themselves really seriously. This year, Kimmel detoured from his usual fake movie trailer to offer up a very funny mockumentary on "The Kimmel School of Perfect Acting," which sees him playing a cross between James Lipton and J.K. Simmons' monstrous teacher in Whiplash. Jennifer Aniston, Eddie Redmayne, Sean Penn, Gary Oldman, Lupita Nyong’o, Emily Blunt, Jeff Bridges, Matt Damon, and many more all show up to be humiliated, berated, and schooled by 'Jim Kimmel.' There are too many LOL moments to list, but if watching Jennifer Aniston fall flat on her back in the name of comedy is something you're into, then these videos are for you.
