Synopsis by Mark Deming
Homer Simpson (voice of Dan Castellaneta) is convinced something has gone wrong with his car one morning, but after stopping at a repair shop, he's told his car is OK -- the thumping he feels is his overworked heart, which is finally pushed over the edge later than day when Mr. Burns (voice of Harry Shearer) threatens to fire him for eating doughnuts while ignoring his work. Homer has a heart attack, and a cardiologist tells him he needs a triple coronary bypass operation; however, Homer doesn't have medical insurance, and simply can't pay the 40,000 dollars the operation would cost. With his options running out, Homer sees a television commercial for semi-qualified surgeon Dr. Nick Riviera (voice of Hank Azaria), who will perform any sort of needed operation for a flat fee of $129.99. Marge (voice of Julie Kavner) is wary of Dr. Riviera's abilities, but Homer decides to go through with the bypass anyway; fortunately for everyone involved, Lisa (voice of Yeardley Smith) did some homework on the procedure before her father went under the knife. "Homer's Triple Bypass" was first aired on December 17, 1992.
