Michael John Kricfalusi //, better known as John K. (born September 9, 1955), is a Canadian animator. He is the creator of The Ren & Stimpy Show, its adults-only spin-off Ren & Stimpy "Adult Party Cartoon", The Ripping Friends animated series, and Weekend Pussy Hunt, which was billed as "the world's first interactive web-based cartoon", as well as the founder of animation studio Spümcø.
John Kricfalusi was born in Canada to a father of Ukrainian descent and mother of Scottish-English descent. He spent his early childhood in Germany and Belgium as a military brat, his father serving in the air force. At age seven he returned with his family to Canada. Having moved in the middle of a school season, he spent much of his time that year at home, watching Hanna-Barbera cartoons and drawing them. Kricfalusi's interest in Golden Age animation crystallized during his stay at Sheridan College, where he attended weekly screenings of old films and cartoons at Innis College held by film archivist Reg Hartt, among them the cartoons of Bob Clampett and Tex Avery, which left a deep impression on Kricfalusi. He soon left Sheridan College and moved to Los Angeles, intending to become an animator.
After moving to Los Angeles, Kricfalusi was introduced to Milt Gray by Bob Clampett, suggesting he should join Gray's classical animation class. Gray was working for Filmation at the time, and soon Kricfalusi found work there as well. His first independent cartoon was a short called Ted Bakes One, which he produced with Bill Wray in 1979 for a cable channel. From 1979 to the mid-1980s, Kricfalusi worked for Filmation and later Hanna-Barbera on various shows which he once described as "the worst animation of all time." He recalls being "saved" from having to work on these cartoons by director Ralph Bakshi, who'd worked with him before in 1981 and 1982. They began working on the designs for the film Bobby's Girl, which was sold to Tri-Star but later cancelled. Under Bakshi, Kricfalusi directed the animation for The Rolling Stones' 1986 music video "Harlem Shuffle".
