Big Bang Theory Quote
Sheldon: Leonard, I have something for you. Per our roommate agreement this is your twenty-four hour notice that I will be having a non-related female spending two nights in our apartment.
Leonard: When you say "non-related female", you still mean human, right?
Sheldon: Of course. Pets are banned under the roommate agreement, with the exception of service animals, such as seeing eye dogs and one day cybernetically enhanced helper monkeys.
