Seriously? OMG! WTF?

When you look at Heather Graham, she appears to be so angelic. Turns out she has a naughty side to her and she likes to tell dirty jokes. Tonight on Conan, she told a joke about sperm that the TBS late night host did not get. Did you get it or is your mind as clean as she looks? Also do you find her humor funny or do you think it blows?
