David Maurice Healy was a supporting character on Roseanne. He was the shy, sensitive, and artistic brother of Mark Healy (played by Glenn Quinn). David Healy first appeared as Kevin Healy in the episode, The Bowling Show, and Roseanne's daughter Darlene was discovered talking to him on the couch. Once Mr. Conner realized it was Mark's brother he offered Kevin a ride home as a joke to get him away from Darlene. Later on, David Healy became more of a regular on the show, and it was made a joke that David wasn't actually the boys real name, and just a name which Darlene made up as both characters became a more serious couple.
