Telle, are you saying that Jimmy could be his own great-great-(some number of greats)-grandfather?
Reminds me of the episode of
Futurama wherein Fry and the others were sent back in time, by an accident, to 1947.
Fry then inadvertently caused his grandfather's death (
before his grandparents' marriage), and his own grandmother unwittingly had sex with him ... :roll:
