Even if it's in joking, most married couples are familiar with the idea of "the list." This is a list of people you are allowed by your spouse to step outside of your marriage and sleep with. The list usually is made up of completely inaccessible people, but Malin Akerman's husband had a rare opportunity to cross one off of his on 'Chelsea Lately' (Weeknights, 11PM ET on E!).
All he would have had to do was show up.
When Akerman said that her husband was a huge fan, Chelsea Handler quipped, "Does he want to penetrate me?" Turns out that he does, or at least finds her attractive enough.
