North died Sunday at his home in Lake Butler, Florida, after battling colon cancer, said Laurie Jacobson, a long-time friend, and his booking agent Bonnie Vent. He called us frequently and ended every conversation with ‘I love you with all my heart’,” Jacobson wrote in a tribute on Facebook. Often wearing a striped shirt and overalls, Dennis’ mischievous antics frequently frustrated his retired next-door neighbor George Wilson, played by Joseph Kearns. Dennis’ patient parents were played by Herbert Anderson and Gloria Henry. North is survived by his third wife, Cindy, and three stepdaughters.
