...but I just looked to see if you could buy a tapeworm online. I have issues slash am so effing tired as I was up dead late last night and woke up for work this morning so I'm semi insane-in-the-tired-membrane today... Apparently, per Yahoo! Answers, you might be able to procure one from a Med Student working in a lab... I was like 2% interested in asking my med student nephew until I Google imaged a tape worm. They are beyond nasty looking.
