Sometimes life needs a laugh track, and this application provides it. Just shake the phone and the audience starts laughing; the harder you shake it, the more raucous the laugh. Canned laughter in your pocket.
Additionally there are sound pads that give you four classic comic sound effects at your fingertips: the rimshot "ba-dum-tschhh"; the infamous Vaudeville "sad trombone"; a slide whistle which is the perfect accompaniment for slipping on a banana-skin; and finally, for when the joke falls flat, the sound of chirping crickets.
