In This episode of Futurama Fry gets infected with Parasites and the crew tries to save him. They don't know that the worms area making Fry into a stronger smarter person. In the end Fry has to make the decision to get rid of the worms or keep them. This is by far one of my favorite episodes.
The Cache you seek is in a nice little spot by the Mississippi River. This is a little trickier hide for more experienced geocachers. Should be some nice scenic views at GZ. No pen in the cache so BYOP!, and this cache has been registered with St. Paul Parks and Recreation. Good Luck Hunting!
