William Michael Petrolle (January 10, 1905 – May 14, 1983) was a world lightweight boxing title contender.

[3][4] Nicknamed "The Fargo Express", Petrolle is perhaps best known for challenging World Lightweight Title holder Tony Canzoneri.

He later owned a religious goods and gift shop in Duluth, and was the chairman of the Board of Directors of the Pioneer National Bank.

The quote reads "In sixty days you'll be fighting Billy Petrolle," the colonel with the big fat mustache roared.

"[7] In this context "fighting Billy Petrolle" was a metaphor for facing combat in World War II.
