In the episode, cast member Charles Rocket was shot in the chest by a sniper while doing a sketch about a sexy couple bathing a dog and spouting innuendo. At the end of the show, during the "goodbyes", Tilton asked Rocket how he felt about being shot. In character, Rocket improvised, "Oh, man, it’s the first time I've ever been shot in my life. I'd like to know who the fuck did it." The improvisation by Rocket, which violated FCC broadcast standards, led to his dismissal from the show's cast.

Personal life

Tilton is approximately 4' 11". Tilton was married to country singerJohnny Lee from 1982 to 1984. She has one daughter, Cherish Lee, born in 1982, and one grandson, born in 2016.

She is currently the ambassador for Actors for Autism, an organization that leads improv and acting workshops for children and adults with autism. She approached AFA in 2010 with the desire to volunteer and has been affiliated with them ever since.
Friendship with Larry Hagman
When she was in high school, while her mother was mentally ill and was raised without a father, the young, unknown actress met Larry Hagman, whom she regarded as a surrogate father. Then, a few years later, at age 17, she auditioned and won the role of Hagman's confused niece, Lucy Ewing, on Dallas. The two had a remarkable on- and off-screen chemistry, for the show's first eight seasons, and they also danced together, off-camera. When she left the show, at the end of the eighth season, her contract had expired, and Hagman was very disappointed about her departure. She said of Hagman, in 1988, "He called me and said, ‘You’re certainly a good actress—we never realized.’ I think Larry went to bat for me to come back on the show." That same year, she came back to the show, and stayed on for two more seasons, until her departure in 1990, a year before the series' finale. After Dallas, Tilton remained on good terms with Hagman, and cared about her TV uncle's failing health, when in 1995, Hagman needed a liver transplant, after being diagnosed with liver cancer, and survived. She did not appear in any of the Dallas TV reunion movies, but appeared in the Dallas Reunion: The Return to Southfork, in late 2004, to reminisce the show's history. Before this, in September 2001, she was the only Dallas member to attend her TV's uncle's 70th birthday; then, 11 years later, she was reunited with Hagman, for the last time, to star in the second incarnation of Dallas. This was prior to her acting mentor undergoing therapy for his cancer. When Hagman died on November 23, 2012, due to complications from myelodysplastic syndrome, she was devastated, and attended his funeral. Upon his death, Tilton released a statement: "At seventeen years old, my life took a turn that one could only dream of. I was cast as Lucy Ewing in the iconic show Dallas. Dallas was so much more than a television phenomenon to me. It was my family. I grew up with a mentally ill single mother raising me and no father figure in my life. I lived on my own in an apartment from the age of 15. I remember the day I met the force of nature that is Larry Hagman like it was yesterday.. My Uncle Larry became the father figure that I so needed and longed for. He taught me how to be professional, work hard, but have fun at the same time, and how to respect the opportunities I was blessed to have been given. He was very protective because I was so young, but also expected the best from me on the set of Dallas. He was one of the best actors the world has ever known. To me, he will always be my Uncle Larry. I am so so very sad, but cherish the lifetime of memories I have with him."
