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.
