The first act of this episode was all over the place, especially the first scene. What was going on there?! Suddenly this long gag is happening, then this long gag, then some plot, then a song, then a tiny bit of plot, now another unrelated gag... keep in mind, this isn't a set of scenes nor breaking them up via cutaways a la Family Guy, just one, bloated interrupted scene.
Luckily it seemed to shape up in the last two acts, but yes, a weak AD indeed. Another episode where Stan and Francine take their martial problems way too far, and then yet another wacky Principal Lewis thingy. I could do without it.
(oh and we never even went back to the gay couple [blanking on names] getting their marriage license)
