Well, Watson is an idiot and a fraud. His female assistant did all the actual work on the DNA stuff. Clearly, since he is a very pale man he is just trying to come up with an excuse for why he could only ever get it up when spanked by a woman wearing orthopedic nurse shoes or something along those lines.
LOL Mojo - not quite. He didn't have a female assistant. He was a young postdoc at Cambridge with too much time on his hands, with a gift for listening to people much more brilliant than he and fitting many snatches of information into a cohesive whole. Which is also a genius of sorts.
What did happen is that he and Crick made use of x-ray work by Rosalind Franklin which showed the helix structure of the DNA possibly without her knowledge and permission, and failing to acknowledge her contribution in the Nobel acceptance speech.
He's also said a lot of silly things in his life. Unfortunately, being a genius in one area doens't make one immune from being extremely stupid in others. Hence, his remarks about race and IQ.
