What producers told censors?
Hitchcock was called by censors to defend himself because he showed toillete bowl in the very same year as this film - in his psycho. they asked him for explanation for that never-before-seen taboo on big screen. not even because of violence or boob under shower.
How on earth censors approved this?
considering a year later fbi investigated song louie louie - coincidentally because of the same circumstances as in this movie - children spread a rumour there is sex/pornography involved inside.
