"Hey, what are you doing?" "I'm salting the roads for ice." "But it's like 90 degrees out here, and it's June!" "I am so fired."
When this and the other episodes were leaked, I deliberately didn't watch them right away so that I could watch it with a good friend of mine whom I'm working on re-introducing the show to. Right when it was over, the first thing she messaged to me was "I think I've seen that episode before."
Obviously, that's completely wrong, and me pointing that out isn't really introducing you to any information you couldn't already assume, but it leads me to my point: this episode was completely passable, if not a little bit samey.
The main premise is that Darwin, seeing Idaho get offended whilst performing what I can only describe as potato torture porn, decides to stop eating potatoes to show support for his friend while Gumball works to help distract him from his withdrawal symptoms.

Admittedly, the middle portion of the episode is a pretty great sweet spot to employ as many jokes as possible, and it's where the episode shines the most. The self-relaxation CD where the narrator himself falls asleep was clever, for instance. Perhaps more pointed was the bit where Sarah, who joins in to help Darwin curb his cravings, shows him aversion therapy, failing on the basis that it was advertising but with different music and a blue tint. Ultimately, though, the highlight of the episode (and, so far, a true standout for the season) was Gumball looking up "Things to do with your hands" to help Darwin find a way to distract himself, only to yell "WOAH!" in shock, and, after some extended silence, "Origami!" There isn't much more to be said on how adept the series is when it comes to subtle (and not-so-subtle, on the occasion) adult humor, but the comedic timing and execution knocked it out of the park. (The two proceeding to fold up Terri's parents was also a nice reveal, if not a bit forced.)
