In G.I. Joe, Cobra created Serpentor by visiting the tombs of some of the world's most famous historical figures and extracting their DNA.

By performing a Reverse Serpentor, you are instead leaving your DNA at said tomb.
I just pulled a Reverse Serpentor at Jim Morrison's grave. Now I feel guilty and could use a quick nap.
