4x11 - Half & Half

Mona realizes that she needs to slow down her relationship with Chase after they start spending so much time having sex that it begins to affect her job and other aspects of her life. Dee Dee plans a "legends ball" on behalf of her mother (who is depressed because of her floundering acting career), but finds that none of the invited guests want to attend. Spencer buys a gigantic new truck that soon leaves him financially strapped because he can't afford gas.
