From a book called Liquor, Lust, and the Law (Aaron Chapman), which is a look at the old Penthouse nightclub and strip joint in Vancouver.
Penthouse owners hired these ladies to streak the Pacific Coliseum in 1974 during a game between the Canucks and New York Islanders.
It was a good idea, I suppose. Thousands of people would’ve been talking about Penthouse for days after. Hopefully all the kids shut their eyes.
