Wow, that was pretty interesting. I like Quagmire getting his revenge. It was a pretty fun twist to reveal that he wasn't Japanese to begin with, and instead was a clever ruse. Along with everything else that happened, like trying to give Quagmire every disease known to man, too bad he has everything. Along with hanging out with Joe. Only FG can make me laugh at domesticated violence so much.
As for the Chirs and Meg making out in the closet, I thought that Optimus would have been Neil, not Chris, way to throw a curveball at me. Still wrong on all levels though, I just love how they tried to cover it up near the end saying they slept with other people. As for Stewie plot, we are actually seeing the devilish side of Stewie make a comeback in some form, but I thought that his segment was the weakest. I wasn't really feeling it until near the end where Lois got back the candy and their way to get around naming the candy.
