It’s said that the more you laugh, the longer you live. After a comedy show at the Groundlings Theatre, you just might be facing immortality. For a hilarious night out with friends in Los Angeles, Groundlings is a slam dunk. Giggle until it hurts on Wednesday nights during “The Crazy Uncle Joe Show,” one of L.A.’s longest-running improvisation shows. Take part in the fun by giving the performers a simple idea. You’ll watch in amazement as they weave it into an intricate, hilarious sketch. Comedy geniuses like Will Ferrell and Kristen Wiig honed their skills right here, and you may be on hand for the birth of a character like Austin Powers or Pee-Wee Herman. Take your crew to “The Black Version” and your sides will split as Comedy Central stars Key & Peele create alternative versions of your favorite films. You’ll howl as they spool the joke out, going as far as outtakes and DVD extra footage, cooked up right on the spot based on your suggestions. When the next big star breaks on Saturday Night Live, or a legend is born on a hit sitcom, you can proudly say you saw them first at the Groundlings. It doesn’t get any cooler than that.
