Sperm donor.
I call this the Ramses Plan. After donating an absolute shit-ton of sperm, I end up with enough offspring (at least 1000) that will eventually spawn my own subspecies of homo sapiens. Instead of homo sapiens sapiens (the current version of humanity) we end up with an extra variable in the population called homo sapiens bohr. In the same manner that most of Asia and eastern Russia is related to Ghengis Khan, most of America and the cool parts of Europe would eventually be related to me.
Bohr sperm FTW!!!
