In 2010, Wendy's released a CD in kids' meals entitled Karaoke Disco Fever, which included Donna Summer's song "Last Dance". The album was later recalled after multiple complaints that a lyric in the song, printed on the CD's lyric sheet as "when I'm bad I'm so, so bad", was actually "when I'm bad I'm so, so horny" on the CD.
Wendy's apologized and said they accidentally used the 'adult version' of the song. However, Donna Summer came out publicly and said she never recorded or performed an adult version of the song, and the lyric has always been "so, so bad". This makes it possible that someone with malicious intent used a method such as sentence-splicing or altering their own voice to sneak the word 'horny' onto the CD.
