Megami33 also cameos as Sailor Moon at the end of episode 4 to comment on her thoughts about Piccolo blowing up the moon.
One of the fake Namekians in Episode 12 off-handedly mentions two guys who "just wanted to play a children's card game," a reference to LittleKuriboh, who by that point had become an official cast member.
Lanipator's brief stint as Freeza is an allusion to voice actress Linda Young. Both Freeza and Yu Yu Hakusho's Genkai are voiced by Young, whom Lanipator's performance is based on.
The character of Guldo is basically Dio from JoJo's Bizarre Adventure Abridged. Antfish... does NOT voice him. But he does voice Ginyu.
Little Kuriboh makes an allusion to his own role as Yami Yugi. When Freeza changes into his second form, he becomes larger and gets spikier horns. It's only appropriate that he uses his DAN GREEN voice for this form. The voice in general is not an allusion, as it predates the Kai dub by months.
In the Tree of Might special, Tien reveals that he is Jewish. Gan Xingba, who voices him, actually is Jewish.
In episode 37, Piccolo thinking up cool names for attacks says "Wind Scar". Lanipator voiced Inuyasha in the fan video "Inuyasha: Episode Infinity."
Revenge of Cooler Abridged references the Japanese version, where Zarbon and Sauza not only fill similar roles, but actually shared the same voice actor in Z (Show Hayami).
Though it depends on which one you watch, since with how popular abridging has become, there are bound to be a few different groups abridging the same thing
Seeing that LittleKuriboh voices Freeza ... at the end of Episode 24, he says "... give me some ideas." He sounds a lot like Florence (a.k.a. Yami Bakura). Interestingly enough, one of his quotes is said earlier in that same episode by Krilin. When he transforms, he sound a lot like Yami Yugi, especially when he says "All done."
Freeza also tends to sound like Marik Ishtar whenever he gets angry, especially when he shouts "I WILL F***ING MURDER YOU!" to Nail.
From the Bardock: Father of Goku special and onwards, many of the sound effects come from the Orange Box. In particular, all grunts and yells of mooks during combat are clearly those of the characters from Team Fortress 2. May also count as a Shout-Out.
Bill Murray also filled in as Yamcha between Vegeta3986 and Faulerro.
In the Bardock special, one of the scientists looking over Goku's pod is Christopher Sabat.
Masako X, Takahata101, and Lanipator all lend their voices to episodes of Death Battle, with Masako X and Lanpinator reprising their roles as Goku and Vegeta respectively.
Creator/Antfish uses his Dio Brando voice (sans the Tim Curry impersonation) for Captain Ginyu.
I Knew It: After Freeza's comment on how Guru can be so fat when Namekians only live on water lead many to believe that Guru caused the great drought by simply drinking it all. They were right.
That the Garlic Jr. Saga would be covered in only one episode.
Insistent Terminology: KaiserNeko is a Troper, and often visits this very page. One of his common quirks is editing instances where other Tropers mistakenly spell Freeza's name as "Frieza". While the official English release usually cites the name with the I-E spelling, in DBZ Abridged, the E-E version is used.
Although, Son Goku has consistently referred to him as "Freezer" in-universe. That's the joke.
Episode 33 parodies this by having Trunks pronounce it as "Fry-za", which is then corrected by Freeza and his father—a bit of Fridge Brilliance when you realize who voices Trunks.
Magnum Opus: For all the abridged writers who contributed.
One of Us: Kaiser Neko is apparently a Troper. He doesn't like it when people misspell Freeza's name either. "Frieza" is the spelling for the FUNimation dub, whereas "Freeza" is the original spelling, used for the abridged series.
Combined with Shown Their Work: The series itself seems to be full of references to inconsistencies and/or food-for-thought points that have been brought up either on this very wiki and/or on popular Dragon Ball fan forums. Such examples include Goku being an absentee father, this running in the family, Piccolo basically taking his place in Gohan's life, Gohan being psychologically messed up from everything he has to go through as a child, clues as to what goes on with members of the Planet Trade Organization when they're not being space pirates, Vegeta being a borderline-heeljerkass even when he's supposed to be one of the good guys—even the differences between all of Dr. Gero's androids in both morality and physical makeup are lampshaded to hell and back.
The Other Darrin: Vegeta3986 replaces Lanipator as Raditz in the middle of the first episode. As of Dragon Ball Z Kai Abridged, Lanipator has gone back to playing Raditz since Vegeta3986 left the show.
And starting in the Bardock special, LittleKuriboh replaces Lani as Freeza (subtly implied when he starts off with Lanipator and coughs mid-line, switching voices when he starts again).
This happened with Chi Chi's casting behind the scenes. The original plan was for Whiteash to handle the character, but she backed out due to life issues before Chi Chi's first appearance. Then Krisrix voiced her for the first season. Now she's been replaced by Hnilmik, a veteran of many popular flash animations, machinima, and adaptation projects as well as voicing Ms. Fortune in Skullgirls. Pick your favorite.
Because Vegeta3986 left the series, everyone he played in the series thus far has been replaced as of episode 24. Kami is now voiced by Weekly Tube Show, and Lanipator has gone back to voicing Raditz (whenever he appears, anyway). This is also going to happen to Yamcha at some point too (if they ever give him another line before cutting him off).
Schedule Slip: Lampshaded by Krillin in episode 24, when he mentions that it feels like they've been on Namek for a whole year.
Specials after the first season would often raise the question of when the second season was starting and harshly shout down the person asking it.
In one FAQ special the question on the schedule for the show was finally addressed... by Bubbles.
Talking to Himself: Even though the cast is significantly larger than most Abridged Series, multiple performance is still unavoidable (Lanipator in particular, who voices Krillin, Piccolo, and Vegeta).
Like the original Japanese version, Goku and Gohan share the same voice actor, MasakoX. Made even more apparent when we see a flashback to a young Goku. He sounds like Gohan, and yet is still able to sound distinct enough to be Goku.
Recoome and Jeice are both voiced by Creator/Ganxingba. And as two members of the Ginyu, they are often talking to each other.
Lampshaded at Youmacon 2009, where Lani intros himself as playing Chris Sabat.
