They turned down Brad Pitt's sperm for Crosby. Imagine being that kid and realizing you could have had Brad Pitt's looks instead of Crosby's. No wonder the kid was a drug addict. 
That actually brings up an entirely new debate. Seriously? How much are guys like Brad Pitt's sperm actually worth? I know that ain't giving it away for free.
Is there an actual market for this shit? Get Arnold Schwarzenegger's sperm for 250,000!
If so, imagine how many kids are not from the genealogy, that their parents tell them.
Wouldn't surprise me one bit.
