* The ending of "Nuts to War (Part 2)" (where Earl tries to snap Robbie out of being a bloodthirsty warlord) is both this and a Heartwarming Moment.
-->'''Charlene Sinclair''': [after the war is over] I heard that somebody got killed.
-->'''Robbie Sinclair''': Yeah, it was some new guy... but you know we could've won!
-->'''Earl Sinclair''': Robbie, what're you saying?
-->'''Robbie Sinclair''': Well, I'm saying it's terrible that guy got killed and all, but you know we had those four-leggers on the run, we could've won it.
-->'''Earl Sinclair''': A boy died, don't you see the fighting didn't solve anything?
-->'''Fran Sinclair''': Come on, Robbie, let's get you out of that uniform, you have school tomorrow.
-->'''Robbie Sinclair''': Forget school, a bunch of the guys were talking about keeping the army together if they came back, they'll set up a base at the swamp so we'll be ready for them next time. They're working on a WHOLE NEW line of weapons, yeah!
-->'''Earl Sinclair''': Stop it! You're not a soldier, you're a kid,
-->''[pulls Robbie into a close hug]''
-->'''Earl Sinclair''': You're gonna go to school, you're gonna take girlfriends to dances, you're gonna drive me crazy like you always have, until it's time for you to grow up.
-->''[A small pause as Robbie comes to his senses]''
-->'''Robbie Sinclair''': Dad?
-->'''Earl Sinclair''': It's allright son, it's over... you're home.
* The ending of the episode "If You Were a Tree", when the tree is blown up by the dynamite.
* The ending of "Charlene's Tale". Charlene's tail grows and she gets a date with a boy, to Earl's dismay. He stays up until late waiting for her and when she arrives, he yells she won't have a date again, to which she just mutters she is okay with it. Both Earl and Fran exchange glances, seeing there is something wrong. Charlene explains it was the ''most humiliating' experience she ever had as the boy met another girl with a bigger tail than hers and left Charlene to walk home alone. This is both a tearjerker (considering how happy she was with the whole deal) and heartwarming due to Earl's speech to Charlene on how the boy wasn't even truly dating her since he left her so easily. He completes saying how he will be there to protect her if she wants and Charlene tearfully replies that she does and hugs him.
* The final episode, especially the last five minutes. A new ice age is forming, the dinosaurs are doomed, and ''everyone''[[note]]except most likely the cavepeople, the mammals, and any species that survived the K-P Event[[/note]] from the series is going to die. But what really drives it home is when Baby asks what's going to happen to them. Earl and Fran don't say anything, but from the way they look at each other, it's clear that they know they're not going to make it. This comes with the unfortunate implication that technology is going to be set back millions of years, as the cave people won't become intelligent enough in time to save it, thus forcing them to reinvent it all from scratch over hundreds of thousands of years.
** The final words of the series.
-->'''Howard Handupme''': And taking a look at the long range forecast: continued snow, darkness, and extreme cold. This is Howard Handupme. Goodnight... goodbye.
* What Fran goes through in "Switched at Birth" is hard not to feel sympathy for. In spite of alarming evidence proving that it is more than likely the case, Fran just can't bring herself to accept that the child she raised isn't her real child. [[spoiler:Fortunately, it turns out in the end that there was never a mix-up in the first place and that the doctor flubbed the DNA test, so Baby actually was the Sinclairs' child all along.]]
