Buttkiss the black Pacu has lived through a lot, from the Summer of Love, to the Cold War, to Y2K, to today. That's right, Buttkiss is 41 years old, and he's a fish. To put that in perspective, the average life span of a Pacu (a type of fish related to the Piranha) is 2 to 20 years. He lives in a Queens pet shop owned by Steve Gruebel and weighs a whopping 20 pounds, eating 20 goldfish a day. His name comes from linebacker Dick Butkus, but Gruebel prefers the more comedic effect of spelling it "Buttkiss." Gruebel calls the fish his mascot, since he's been around the shop for so long. However, he has no idea why the fish keeps on keepin' on after doubling his life expectancy.
