Now, it's important to realize that Lamar refuses to answer the house phone. So when the phone rings for half a ring and Lamar quickly grabs it, Khloe starts to figure something is up. We know this because she makes this face:
Khloe's suspicions are correct - Lamar's BFF/hangeron Jamie has a girl coming over and they don't want Khloe to find out because she just does not tolerate that shit. Remember how the idiot Celebrity All Star brother was being all territorial and shit? He decides to blow up Jamie's spot by loudly asking "hey Khloe, why is Jamie allowed to have girls over and I'm not?" Khloe is livid at the thought of Jamie inviting a girl over. We know this because she makes this face:
Breaking the 4th wall, Khloe tells us that her house "is not going to become a free for all" and she's "not going to allow all these whores to come over."
Lamar is stunned by this ph33nix level of snitching and asks the idiot Celebrity All Star brother to grab him a banana and to "fuck me with it cause you just fucked me." Lamar then thanks his brother-in-law for fucking him with the banana.
