To this day, I’m astounded by the “hipness,” cleverness and outrageousness of “Rowan & Martin’s Laugh-In.” The fast-moving, rapid-fire, one-liner sketch comedy show (with awesome musical performances thrown in) was groundbreaking when it debuted in 1968. Now, Time-Life has made “Rowan & Martin’s Laugh-In: The Complete Series” available on DVD for the first time.
