Why Clark Kent & Lois Lane Should Not Have Sex

I know Bryan Singer's film Superman Returns allowed the premise that Superman and Lois could conceive a relatively "normal" child, but all comic book fans know the truth.  Superman and Lois were warned that creating a kryptonian and human hybrid off-spring would be disastrous. The only benefit from their selfish misdeed was we got one of the stars of Goonies.  Chunk with super powers is scarier than Bizarro.
