Studies have suggested heavy use of Margarine can cause one to develop extremely large whip-worms, from larva imbedded in Margarine during the manufacturing process.
In several cases involving affected patients, they had to be placed on their stomachs with their mouths propped open. Raw meat was placed just outside the mouth and when the worms exited the mouth towards the meat, the worm was actually grabbed by the physician and pulled out in order to remove the giant parasite.
LOL! That is the funniest thing I have heard in quite a while!
That reminds me of the old Amish cure for worms, which is to sit in several hallons of milk for a couple of hours. Supposedly when done the milk would be filled with the worms that were enticed to come out for the milk. Yuk, but maybe effective! Many will do this once a year.
