Production notes mention the Italian Guardia di Finanza (a gendarmerie specialized in financial crimes) once managed to arrest Arcueid Brunestud, Nrvnqsr Chaos and Roa. Why is this here and not among the awesomeness? Because of how it happened: Arcueid simply let herself get arrested because she knew she would get out soon enough and becoming a wanted criminal could have caused her unneeded distractions, Roa's arrest consisted of him getting shot a dozen times and the Guardia di Finanza complaining about their weak sidearms when they saw he was still alive (to be fair, the pistols they used at the time of the incident were underpowered), and Chaos laughing until he fainted when they ordered him to stand down. They still got a fearsome reputation out of it (because Roa couldn't say anything to anyone, Arcueid doesn't care of setting the record straight, and Chaos was too ashamed of what happened to reveal he wasn't really defeated in some epic battle).
Mio Kuroki's Heroic BSOD in "Addestramento Sailor" ("Sailor Training") when Seiya mentioned Minako in her presence.
The explanation of why the Shitennou hated each other: they used to be friend, but one day the friendly competition between Zoisite and Nephrite led the former to create Mio and Nephrite, following the advice of a drunken Jadeite, created five perverted tentacle monsters. It degenerated from there.
The final scene has the narration mentioning that the battle in which Sayaka just died had been against Quitterie and noting that Homura had been really enthusiast in hitting her face.
The scene before that has Elyon remembering Cedric's description of Meridian's economy as ruined by "over ten years of your brother who can't administer fucking anything but listens to imbeciles. Yes, my main qualifications are as soldier and librarian, but how is it that my theorical knowledge makes me less qualified than stupid nobles who can't even administer their allowance?!".
In an omake, Madoka, upon Sailor Venus' suggestion, wishes to Kyuubey to transform into Heroic Spirit every single character in the song The Ultimate Showdown of Ultimate Destiny plus Bruce Lee, and sick them upon Chaos. Ten minutes later, thanks to the power of the Chuck Norris Facts, Chaos had been annihilated, after which we see a scene of chaos in which Minako trying to drive Optimus Prime, Batman cheating while playing cards with Superman and Puellae Magi recharging their Soul Gems under the Care Bear Stare are the less insane things happening.
