Hello curlyzone - I think out the rear is less tramatic to a person's mental state of health! I am glad you have heard of this too - I had another poster in another just about scream "QUACK" at me and I was trying to defend myself with the post I copied here. I had told a very scared lady that what she MIGHT have trying to come up her throat and nose was a tapeworm. It does not happen very often that they get very, very big and decide to travel - but it DOES happen. Thank you!
