When I was in grade school, I was an alter boy, and I remember getting calls like that, the voice always sounded like Father Ironrod.In college, we had a special telephone system that let you call the dorm you wanted and the specific room number. We would call girls at random and in our best British Monty Python voices, "Hello, this is an obscene phone call. Please state your preference, rank, semi-rank, or slightly suggestive."
