Am I excited about the upcoming (January 22) 50th anniversary of the groundbreaking NBC comedy-variety series “Rowan & Martin’s Laugh-In”?You bet your sweet bippy!Stars such as Arte Johnson, Ruth Buzzi, Lily Tomlin, Judy Carne, Goldie Hawn and Jo Anne Worley made “Laugh-In” America’s #1 show for two of its six seasons. Although some of the bawdy repartee and ripped-from-the-headlines political satire (about the Pill, the anti-war movement, smog and the drug culture) went over my innocent little head, the breakneck one-liners and zany sight gags brightened my Monday nights and made quite an indelible impression.The show left such an impact on my generation that even a year or two after it went off the air, members of my class at Connelly Junior High School threw together our own version of “Laugh-In.” I hammed it up playing announcer Gary Owens (broadcasting from “beautiful downtown Burbank”), but the undeniable highlight of the presentation was a spoof of Big Wally foaming cleanser, with Joel Hargrove bursting through a (fake) wall to rescue a beleaguered housewife with the must-have properties of the miracle product.The nickname “Big Wally” stuck with Joel.
