How do Hollywood’s biggest stars keep their acting chops solid?

By attending the Kimmel School of Perfect Acting, of course, with acting teacher Jimmy Kimmel’s unorthodox training honing the skills of such stars as Jennifer Aniston, Mila Kunis, Jeff Bridges and even Kimmel nemesis Matt Damon.

Among Kimmel’s unusual techniques: “smacting,”; in which an actor is encouraged to perform better by being smacked on the head with a pool noodle while Jimmy says, “I don’t believe you… you can do better.”;

As Sean Penn admits, “The pool noodle is the only way I can learn.”;
