Flies are on 3 different episodes, and are #1 on Gross Outs, #9 on Cleaners, and #5 on Dirty Jobs. They have to throw up on whatever they eat in order to digest the food. They also lay their eggs in dead flesh. A maggot can strip a carcass in days. Maggots are also used to treat people in hospitals. They sterilize the maggots with antibiotics. Since they only eat dead tissue, they help healing wounds. They are armed with hooks in their mouths and their spit contains enzymes that turn dead tissue into a soup. Flies also clean themselves by rubbing their body with their legs. Since they taste with their toes, they don't want the remains of their lunch clinging to their feet. Their eyes also have no lids, so flies are constantly rubbing them to keep them clean.
