Stan and his near-clones all comment that "Burt Bacharach seems like he should be dead by now".
Burt Bacharach is a Grammy winning singer and composer, his songs have been featured in numerous films and TV series, he is also well known for composing the soundtrack to
Butch Cassidy and the Sundance Kid (1969) and for his cameo appearances in
Austin Powers: The Spy Who Shagged Me (1999) and
Austin Powers in Goldmember (2002) where he sings along with
Mike Myers. Unfortunately Stan's statement is a bit prophetic as Mr. Bacharach died on February 8, 2023 at the age of 94, less than two years after this episode aired.
