A dancer’s career often involves injuries. Comedian Rita Rudner started as a dancer on Broadway, until she suffered an injury. “I pulled a groin muscle,” Rudner said in 1988. “It wasn’t my own.”
   
Rudner sometimes changed the story slightly to, “I got kicked out of ballet class because I pulled a groin muscle. It wasn’t mine.”

Rita Rudner (born September 17, 1953) is an American comedian, writer and actress. Beginning her career as a Broadway dancer, Rita Rudner noticed the lack of female comedians in New York City and turned her stage presence to stand-up comedy where she’s flourished for over three decades. Her performance on a variety of HBO specials and numerous appearances on the Tonight Show with Johnny Carson, helped establish Rudner as one of the premiere female comics to emerge from the comedy boom of the 1980s. After extensive touring throughout the past 20 years, Rudner has created a steady career performing in Las Vegas at the Venetian Hotel while residing in Southern California.
         
2 February 1988, The Orange County Register (Santa Ana, CA), “Film fest features madcap comedy” by Vern Perry, pg. F2, col. 2:
From dance to laughs…
When comic Rita Rudner, who opens a five-night stand at the Improv in Irvine Wednesday night, started in show biz, she was a Broadway dancer at the tender age of 16, kicking up her heels in such musical as “Follies,” “Promises, Promises,” “Mack and Mabel” and “Annie.”
 
Then, tragedy struck and Rudner was forced into early retirement as a hoofer. As she describes her debilitating injury, “I pulled a groin muscle—it wasn’t my own.”
