You know, the plot of this episode sucked. I mean, totally totally sucked in terms of it being a typical "Stan-is-a-jerk-but-learns-in-the-end-with-a-sincere-i-can-change-speech", but what happened during the middle, and the sheer number of hilarious jokes dealing with Stan and his robot double more than make up for it. I laughed heartily when he just destroyed that Tootsie Roll mascot, Chad Lowe, Augustus Gloop, the internment camp, and Francine's aversion to paying $23.00 for a photo at the Tunnel of Love. Shame really, I would've shelled out the dough for it.
Only other rough spot was Steve and Roger's subplot. So much potential wasted. Had Roger not been there, maybe something could have been yielded from it. Although thankfully we do get to know Toshi's parents (unless they've already appeared in another episode that I didn't see).
