Colin Mochrie and Brad Sherwood, improv comedians from the Emmy-nominated "Whose Line Is It Anyway?" head to the Coral Springs Center for the Arts (2855 Coral Springs Drive) Saturday for a night of off-the-cuff bits. The men, who currently appear on the CW's resurrected improv show (the new season will begin on March 21), will no doubt include memorable "Whose Line?" bits such as "Mouse Trap," in which Mochrie and Sherwood, both barefoot and blindfolded, cross a stage littered with live mousetraps. 8 p.m. $40.28-$61.48. 954-344-5990 or CoralSpringsCenterForTheArts.com.
