Uncle Sticky is (apparently) the son of Ephraim Wanker and Peg's Mom and Peggy Bundy's brother, Al Bundy's brother-in-law and uncle of Kelly and Bud Bundy and the adopted uncle of Seven. He is never seen onscreen, but in the Season 9 MWC episode "Kelly Breaks Out", Sticky is mentioned as the concocter of the zit-removing potion which may be the answer to Kelly's prayers, although the consequences of Wanker concoctions are also brought up by Al.
