What's the difference between a Catholic priest, and a Boy Scout Scoutmaster? One is called father, the other is called daddy. How are they similar?. They both rape you.
Why make this joke about Catholic priests?
Because I want to remind the world that catholic priests are rapists.
Well it's wrong to joke about them being pedophiles. That's just born from a bad stereotype and it's simply not the case for the vast majority of them.
