* There is the scene of Bugs letting Taz go back to Tasmania where he belonged. It was saddening to see how these two Looney Tunes characters that bonded together throughout "Devil Dog" had to separate. [[spoiler:Fortunately, it becomes happy tears when Bugs finds Taz had snuck on the plane to return to his new friend and master.]]
* Pretty much anytime we're reminded of [[TheWoobie how lonely Porky is.]] [[DudeNotFunny And it's always]] PlayedForLaughs.
** Especially when [[JerkAss Daffy]] took all of his money and left him broke. Who ''didn't'' want to give him a hug?
*** Made even worse by the fact that, after all that, he untied Daffy simply because Daffy called him his best friend and said he'd give him a hug. (He lied.) And at the end, it's revealed that [[spoiler:Porky donated his kidney to Daffy]], and [[spoiler:Daffy forces him to help fix the parade float even though he still feels weak from the surgery]]. Let's hope Petunia makes an appearance soon, because Porky's life could ''really'' stand for some improvement.
*** Petunia finally shows up in what has become a series of episodes where things actually go pretty well for Porky.
* Speaking of losers, Daffy was always a bit insecure, but in this series he becomes pathetic to the point of JerkassWoobie-dom. On his date with Tina, she guesses (correctly) that he cries himself to sleep every night. She then decides that he's not ''completely'' hopeless and compares him to a terrible, run-down building that needs to be demolished before it can be rebuilt. Daffy tears up and says, ''"That's the nicest thing anyone has ever said to me!"''
** Also doubles as a serious [[SugarWiki/HeartwarmingMoments Heartwarming Moment]].
* Sylvester's flashback to his childhood in "Point, Laser Point".
* Daffy saying goodbye to baby Zachary.
* Daffy's KickTheDog moments toward Porky in "The Shelf".
* Speedy discovering "Cathy" is Bugs. He plays it off like he was just being nice to an ugly girl, then weeps once he's in his room where we see he was planning to propose.
* Oddly enough, "Dear John" gives us a pair of sad moments when Lola and Bugs (individually) think the other has broken up with each other. If anything, it shows that after all this time, they both care about each other, and losing each other is a serious thing for both of them.
* In "You've Got Hate Mail", Daffy calling Tina a [[RefugeInAudacity psychopath]] turns heartwarming once it's revealed that he just thinks that anyone as wonderful as her would have to be crazy to love him... until you realize what this implies about [[InferioritySuperiorityComplex Daffy's self-esteem]].
* This series ended up being the final time Creator/JuneForay voiced Granny prior to her death in 2017.
