Pretty good advice but I don't know if I could use the butt suggestion, even though it would he a great aid for pin worm problems.
I have seen people expel 5 gallon buckets of pin worms out, people have no clue how bad they actually can get and I assure all people reading this, WE ALL have X amount of pin worms at any given time regardless what we do. They multiply rapidly and live everywhere and God help those with pets in their houses!
