Improvisational comedy is either very funny, or it’s like reading a LaToya Jackson biography: You’re not sure what’s going to happen next, and you don’t really want to find out. Even good improvisational comedy troupe can have a horrible show. Anything could happen, and that’s both the attraction and the danger of improv comedy. Four day Weekend is one of the few comedy troupes in the area that is consistently funny within the loose constraints of improv comedy, managing to keep the audience laughing with them instead of at them. After a successful year at Casa Manana’s Theater on the Square, the improv troupe – which features David Wilk, David Ahearn, Frank Ford and Troy Grant – brings its fast-paced, audience driven brand of improvisation into the newly dubbed Four Day Weekend Theater starting on Friday. The show features the debut of Four Day Weekend’s new musical director, former Ten Hands member Paul Slavens.
