Overall the season has been somewhat strong, but this episode had all kinds of stuff wrong. Firstly Marge cheating is out of character for her, when she has been dishonest in the past it was a Marge episode and the writers worked hard to have her learn a lesson & have her overwhelming guilt set her soul free. Here, she simply isn't sorry enough or go through enough storyline to justify such a major cheat. Next, Homer vomits in a bush because he feels guilty for "ruining" Marge with dishonesty. The joke is jarring, belonging more to a bad Family Guy joke, but for a sweet show like the Simpsons really lowered the class of the episode... a brand new low. Vomit jokes are usually not funny, it wasn't funny before with the Harry Potter frog puke joke and it isn't funny here. Then, to double down on the stupidity Cletus does a call back to the vomit joke which again doesn't work. Somebody has got to be in a position of authority to stop these kinds of jokes from getting through. It was really bad.
