Susan Boyle is a Scottish singer who became famous when she stunned Simon Cowell on the British show, the Britain's Got Talent with her singing.
She is referenced in "Fatbeard" by Ike Broflovski who says that he would "vomit his balls out through his mouth" if he heard one more thing about Boyle's performance of "I Dreamed a Dream" from Les Misérables in Britain's Got Talent.
The Boyle reference in particular received a great deal of media attention the week "Fatbeard" first aired.
