Wrestle Mania (1999)

Oujin, Ebizuka, and Dr. Gyosei repeatedly kidnap playboy celebrities and perform sterilization surgeries on them to make them incapable of bearing children. They declare that homosexuality is the correct 21st century ideology on the basis of their insistence that the population of the earth should not increase any further. Butterfly, their new prey, is actually gay, and says he agrees with their ideology and wants them to join him... Slippery, slippery, and slippery.
