What I liked: "He's sleeping in the pantry!" "With a gay roommate, we can walk around naked!" "Way ahead of you" (Homer walks out naked), "That was the best kiss I've had tonight" (and then he thinks to himself "or was it?"). Amongst other things.
This episode had a lot of gay jokes, but what do you expect when the episode is centered on gay characters? Not all of the gay jokes were funny but a lot of them were, and as such, I think it is fair that my final grade for this episode be a B+/A-. Not the best episode of course but it was still really good.
