When it gets cold outside most men suffer from shrinkage, but not Simon Cowell. His nipples get harder than a diamond! As witnessed yesterday during Conan’s TBS late night show when we got to see what happens when the lone X Factor judge’s shirt braved the frigid temperatures in LA. Those things could not only take out an eye, they can also get a girl pregnant. So ladies if you see the King of Mean on a cold day, I have one word of advice…run!
