Everything may be made up, and the points may not matter, but the improvisational comedy formula of Whose Line is it Anyway? has been reliably gut busting for more than 30 years. A decade after the series’ UK debut in 1988, its American counterpart continued to popularize improv comedy and enjoyed a recent revival on The CW in 2014. In mid-December, San Antonians can offer their own suggestions for these quick-witted comedians to act out in imaginative games and musical mischief. Featuring the seminal and famously well-shod Ryan Stiles, major recurring guest Jeff B. Davis, American TV actor Joel Murray (Mad Men, Shameless), Canadian comedian Dave Foley (The Kids in the Hall, Celebrity Poker Showdown) and the musical stylings of Second City veteran Bob Derkach, the live improv tour seems equipped to bring down the house.
