** "Gore On The Shore" is also heartbreaking, being a duet between two ex-lovers who drifted apart due to circumstances beyond their control and don't know whether their relationship will ever be the same again. The fact that said ex-lovers are anthropomorphic oars will ''not'' stop you from bawling.

** The final moments of "The Demonic Possessions of Loudun" are one big tearjerker. The Genie ''[[TheBadGuyWins wins]]'', not only returning all the guests back into the inanimate objects/animals they once were (essentially ''killing'' any of them that hadn't already been alive), but throwing The Professor into Cretaceous times where he's eaten alive by a T-Rex as well. For those who have watched the show since the beginning, seeing our beloved host canonically killed off can trigger quite the emotional response.

** Shane warned people that “Pieces Of Me” was genuinely emotional, even comparing it to later Hot Daga, and he wasn’t wrong. You WILL feel bad for a coin.

** Jose's Book has a song that's rather quiet and quirky, but between the ominous clock ticking and the Book's final line (where it mentions that reading too much could cause jerks to want you dead for it, all while the music cuts out) you get the impression that the Book is rightfully resentful of its former master's death.

* During "The Grisly Journey of The Donner Party", Ryan, The Professor, and special guest Joyce start talking about modern day Reno. The Professor mentions he vacations there, at which point Joyce suggests they could go together some time. The Professor sounds absolutely ''delighted'' at the prospect, and the two agree to plan the trip after the episode.
** Making it even more heartwarming, the second episode to feature Joyce, "Ching Shih: The Pirate Queen", reveals that they did end up going on that trip together! Aww...
** The oar's song from the Christmas special, where it's revealed that not only did they get back together after the Musashi episode, but they're now traveling the world and creating a future all of their own. After how miserable the two were after they were separated, it's nice to see them be SickeningSweethearts.
--->'''The Two Oars''': Every trip you take is a gift/when you love the livin' hell outta the one that you're with!
** Kate is so moved by her Christmas gift from the Professor in the St. Nicholas episode that she cries.
-->'''Kate''': This is honest to god the sweetest present ... and uh-oh, I haven't cried properly in a minute... ''[cries]''
* The song at the end of "Ching Shih: The Pirate Queen" is a surprisingly normal-sounding folk pop/rock song by the flower boat that Ching Shih worked on before her piracy career, in which he admits that he's a little sad and jealous that she's moved on to bigger and more exciting things - but is overwhelmingly happy and proud to hear of how wildly successful she's become, in a similar manner to someone reflecting that an old friend's gone on to fame and fortune, and comments that she can always visit him again in her retirement if she'd like. It's a pretty touching and genuinely ''nice'' song for a serenade from a literal boat to a ruthless pirate in a comedy puppet show.
* In "America Vs. Smallpox", when the Professor reveals that smallpox had a fatality rate of 30%, Ryan realizes that one out of the three people in the room (him, the professor, and Jermaine) would have died, and immediately states that he would take the fall for either of them because he thinks they're "both really nice guys." It [[MoodWhiplash becomes a lot funnier]] when the Professor has little to no reaction to this, however.
* In Season 5, it turns out that after the Professor was swallowed by the T-Rex in Season 4, he was reborn from an egg to her and her [[InterspeciesRomance pterodactyl partner]]. The whole deal is very much played for laughs when it's first introduced in "The Vietnamese Sisters Who Fought An Empire", but the unconventional family gets a surprisingly sweet scene at the end of the next episode, "America's First Black Aviatrix", wherein they're stargazing together, the Professor teaching his new parents about space before his "dad" suggests they all start making up their own constellations together. The T-Rex makes one up of a bird that she claims she found the song of uplifting on especially hard nights incubating his egg; and the Professor makes one up of Ryan, who he happily describes as his friend and who he reflects he wasn't always especially kind to. His "mother" understandingly comments that people sometimes do nasty things out of carelessness, and he admits that he'd like to reconcile someday. It's honestly pretty touching as a bonding scene ''and'' as CharacterDevelopment.
