The Groundlings Theatre has been serving up improvisational comedy since 1974, keeping audiences in stitches every night as well as launching the careers of top film and television comedians including Melissa McCarthy, Will Ferrell, Kristen Wiig, Jennifer Coolidge, Will Forte and Kathy Griffin. Head in on Wednesday nights for "The Crazy Uncle Joe Show," one of LA's longest-running improv shows, as seven comedians take random suggestions from the audience and spin them into hilarious skits. There's plenty of other show choices all week long and The Groundlings even do a comedy session aimed directly at children – designed for kids starting at age three and going to about ten. And if you want to learn to be an improv comedian, enroll in The Groundlings School and you'll soon be on your way.
