It’s graduation night for the Grapevine High School improv comedy class! There’s just one small problem: the drama teacher fell sick at the last minute. Luckily the high school football coach, Ted Rookard, has volunteered to direct the show. He’s got a sports-minded attitude and a brand-new copy of “Improv for Dummies.” What could go wrong? Work your own improv magic with cast members! No ticket needed, just hop in.
