I had only been working a week or so when I got a call from a very quiet man asking for a therapist who was out of the office. I told him he was not in and asked for his name and number and if he'd like to leave a message. He became really agitated, almost frantic, and was pausing after every few words then finally blurted out, "I can't stop masturbating!"
I freaked out (can't recall what I said - it was either, Ewww! Oh my GOD! or Pervert!) and hung up on him. I ran into my sister's office and told her about the obscene caller.
After we had a laugh with a couple other co-workers who popped in to see what was so funny, my sister asked whose line the pervert called. I told her it was one of the therapists. She got all serious and asked which one. I said Dr. McKay. Her eyes bugged out and she said "OH NO!! He's a sex therapist!! That wasn't a crank call!"
We still laugh about this now and for all we know the guy's still masturbating because he never called back.
