American pop singer Britney Spears guest starred in the episode as herself. According to Scully, she was seventeen to eighteen years old when she recorded her lines, and "She was a lot of fun to work with. She was a fan of the show, and she was willing to do all the lines. It was all the people around her that were crazy, the management and all that. We originally had her introduce herself the episode as 'I'm teenage songbird Britney Spears.' And she recorded a few takes and they were fine. And suddenly, all these guys come rushing in 'She can't say songbird.' [We asked what's wrong with songbird? And they were somehow convinced that it was some sort of slam or an insult." The staff members were therefore forced to change her opening line to "I'm teen sensation Britney Spears."
