Shenanigans was an American thoroughbredmare born in Kentucky. She was sired by Native Dancer and out of the Locust Hill foundation mare Bold Irish. Owner Stuart Janney Jr. recalled, "Shenanigans was meant to be a good mare, she had speed and she was second to Miss Spin in the Maryland Futurity, but she developed a little calcium in a knee. She raced a little bit at three, but we decided she wasn't going to be able to win a stakes, so we stopped with her." The Janneys considered sending her to Bold Ruler for her first season, but she was sent to Knightly Manner instead and failed to conceive. The next breeding was with Neartic. This resulted in the gray Icecapade, who was a successful stakes racer and sire. In 1970, Shenanigans foaled another gray, a filly named Laughter who like her mother excelled in the breeding shed when she beget horses like Private Terms but was at best mediocre on the track. In 1971, Shenanigans was bred to a son of Bold Ruler, Bold Lad, which resulted in a colt, On To Glory, who was a winner but not a stakes performer. He did, however, produce a couple of graded stakes winners while at stud. In 1972, Shenanigans foaled her most famous progeny: a brown filly by Reviewer named Ruffian. This tall, almost jet black filly destroyed track and stakes records for two seasons before she broke down in a match race against Kentucky Derby winnerFoolish Pleasure. Many claim that Ruffian's tragic end was a product of her breeding. Her sire broke down four times: three times while racing and the last time in a paddock accident where he re-broke a fracture he had sustained a few weeks earlier in another barn accident. After Ruffian, Shenanigans had two more foals: a stakes winner and sire in 1974 called Buckfinder, by Buckpasser, and one more winner in 1977 named Near East, by Damascus. She was named Kentucky Broodmare for the year 1975. On May 21, 1977, Shenanigans died similarly to her daughter when she awoke from anesthesia after intestinal surgery and began to thrash wildly, breaking two of her legs. She could not endure another surgery and was euthanized.
