Years ago they said there was blood in it because a guy working at the pepsi plant fell off the scaffold stretched along the top of the syrup vats, this worker was missing for months and assumed he left town and was never heard of again, then months after his reported missing, they drained the stanless steel vats for routine cleaning and they found a skeleton at the bottom.. So the myth goes on that for many months people were drinking pepsi laced with human remains.. Of course this was argued by Pepsi as a hoax and some people even claim the rumor was started by employees of Coca-Cola.  Timeline 1950's..  (disclaimer- This is a myth, its never been proven.)
