John Ritter, as the character Jack Tripper on the ’70s sitcom “Three’s Company,” may have let something slip in one episode, it turns out. According to reports in the New York Observer and on MSNBC.com, an anonymous viewer who watched very (as in VERY) carefully and then alerted Nickelodeon, which reruns the show, that there was something, well, funny in a scene. In it, Ritter, wearing blue boxers, plops down on a bed, and “His scrotum falls out of his shorts,” acknowledged a Nickelodeon spokesperson, adding that the offending moment has been deleted from future broadcasts. Ritter, now 52 and starring on Broadway in Neil Simon’s “The Dinner Party” (with Henry Winkler), told the Observer that he’s not bothered by the scene. “I’ve requested that (Nickelodeon) air both versions, edited and unedited,” he said, “because sometimes you feel like a nut, and sometimes you don’t.”
