Adam Overberg, Paul Workman, and Joseph Maubach in The Complete History of America (abridged)The Harrison Hilltop Theatre's The Complete History of America (abridged) is moronic on the surface, yet has undertones of sharp wit. While Chris Walljasper's direction makes the show play like a frat-boy presentation on the history of North America, there's also an intelligence to the humor, which mixes pop-culture references - from Super Mario to Lady Gaga - with historical events from the past 50,000 years.
