She was sired by Native Dancer and out of the Locust Hill Farm's foundation mare, Bold Irish.
[1] 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.
In 1970, Shenanigans foaled another gray (this time by Bold Ruler), 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.
[2] 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 winner Foolish Pleasure.
On 21 May 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.
