The amazonians.
Fry: So, what’s it like on planet Amazonia?
Amazonian: Big rats there. Me crush with club!
Fry: That’s so interesting. Perhaps we could talk more over a cup of coffee?
The robot cop, don’t know what his name is.
“Continuing undercover chase…baby.”
Roberto, the insane robot.
Roberto: Now stand back, I gotta practice my stabbing! What’s the matter, you scared?
Fry: N-n-n-n…
Roberto: Noticeably? I’ll say!
Robot Santa.
“You’ve all been very naughty! Except for you Zoidberg, have a pogo stick.”
Also, Flexo.
(After being punched by Bender) Flexo: Hey thanks buddy, I appriciate that. Nah, I’m just yanking your chain - that was really quite annoying.
Human Cop: “Try the ol dine and dash, huh? You punks make me sick. My dad had a restaurant once, and its jerks like you that kept him from going reigonal!”
Also, Kiff is funny…in the Bugaloo episode:
Kiff: “I don’t have any bones. I’m actually supported by a system of fluid-filled bladders…”
URL, though I didn’t realize that was his name until reading this thread. “It’s a stone cold shame.”
I love Zoidberg… sometimes I even do the woop-woop-woop noise when I’m driving, to let my passengers know I’m about to do something questionable. But I’m shocked and saddened to see him called a minor character. I didn’t think there were any episodes without the doctor.
According to the DVD commentaries, she’s named Hattie. I think all the characters (at least those that reappear) have names, although sometimes they never made it on the air. Sal, for instance, I don’t think was ever named.
Morbo, hands down. I haven’t watched a network newscast in, well, ever; if they had a newscast hosted by an alien who openly despised humanity and rooted for its destruction, I’d be tuned in every night.
Favorite Morbo moment: the earth is in the grip of a global heat wave.
Morbo’s co-anchor: “I’m sure those windmills will keep them [Dutch tulips] cool!”
Morbo: “Windmills do not work that way!!” (Turning back to audience) "Good night!!"
My favorite of these is when she and the Professor are arguing during the robot revolution (right before they tear each other’s clothes off) and she’s so frustrated she can’t construct one of her usual complex insults, but she still gets in a little extra:
Hi-larious!! My husband’s favorite is with FinnAgain, Hypnotoad. As for myself, I don’t think I could select just one. I do like Malfunctioning Eddie, who when he was informed he was being released from Robot Asylum, had a little explosion on his shoulder and said something like, “Look, I barely exploded at all!” and the DoctorBot says, “We can control that with medication.”
My husband tells me that my favorite secondary character is the Hypnotoad. Everyone’s favorite character is the hypnotoad. All Hail the Hypnotoad .
Three great minor characters who I don’t think have been mentioned yet are Zoidberg’s lawyer from the flag eating episode (“Give me a Satanic funeral.”), the President of the Neutral Zone (“If I don’t survive, tell my wife I said hello.”), and the Dean of Mars University (“Robot House!”).
