Homer finds a note from way back,which implies that Marge never really loved him,so he moves out and shares a condo with two gays,Grady and Julio,adopting gay mannerisms and ultimately discovering that Grady is in love with him. After being admitted to hospital for alcohol poisoning he is shown video evidence by Dr. Hibbert,which proves that Marge loved him all along,and returns home.
