Are you killing it on amateur night at the comedy club? It's more likely that the audience is about to kill you. That's why the Laugh Track Jacket may save you. Becky Stern of Adafruit developed this comedy aid. It's an audio soundboard with a thin 4-button keypad. When you need some support, click the appropriate button. Stern selected canned laughter, crickets chirping, and a foghorn. But it's a customizable system, so you can choose any sound file.

P.S. Now let me pitch my idea for a horror movie: a man wakes up one day to discover that there's a laugh track for his life--but he's the only person who can hear it.
