Ah, improv comedy: the slacker's favorite alternative to writing comic material with any deep thoughtfulness. Improv, however, shouldn't be simply discounted as being lesser than any other true comedic artform. It takes a certain wittiness, recalling ability, and fertile repertoire by which comedy can be engendered on the spot. An improv comedian is always on his toes and tapping every resources available, intrinsic and extrinsic (e.g. the scene, given characters, verbal cues, etc.). Some improvisers can adapt the art to fit an entire 90 minute stand-up routine (i.e. Robin Williams, with the help of 800 water bottles in lieu of former coke habit), while others work as a troupe or cast in a show (live or televised), consisting of a series of games that come straight out of some manual. While Whose Line Is It Anyway? is the most recognizable source of improv exposure (due a lack of televised competition), improv theater is a big thing in big cities and a heavily-tapped resource for SNL cast members (Second City, Upright Citizen's Brigade, Groundlings, etc.). While Whose Line opts to only display a topical sampling of what can be found in an improv performance, here is a sampling of some of the best participation-friendly improv games that both can and can't be found on any rerun of the series (in either case fun to play in any acting class or at any party in need of some liveliness).
