Haley Reed : Big Bang The Orgasmic Dissension
Penny and Leonard are looking to take their relationship to the next level by asking Sheldon to move out so they can have more time together. They order Japanese food to help soften him up, then broach the subject. Sheldon takes things more calmly than they were expecting, but he does bring up their roommate agreement. When they moved in together, Leonard signed an agreement stating that if he asked Sheldon to move out over a girl, Sheldon would get to have sex with the girl while Leonard watched. Penny agrees.
