I saw a Second City improve last winter, and one of the better sketches exploited Facebook similarly, albeit in a more lighthearted and humorous way.<p>Prior to the performance they would find an audience member's Facebook page using their credit card or mailing address (presumably), and write a sketch based on the details extracted from his or her page.<p>They incorporated the lucky patron's inevitable reaction into the sketch under the pretense of reprimanding him for disrupting the show. After letting him squirm a bit under the spotlight, the punchline was projecting his Facebook page on the screen across the stage.
