30 Rock

When Liz shows Jack a picture of the very attractive Dr. Drew Baird, Jack snidely wonders aloud if the attraction Drew has for Liz is because he is a "Bundy-esque serial killer", referring to Ted Bundy, who's good looks were a focus when he was discovered as a serial killer in the 1970s. Later in the episode, as Drew's mother lay dying, she tells Liz that she must tell Drew that the woman he believes to be his sister is actually his mother. This is likely another Bundy reference, as he was made to believe for many years that his grandmother was his mother, and that his actual mother was his sister.
