Agreed, it was not great, it was only ok.
In the past couple years I think I’ve seen each episode at least three times on Adult Swim. I suspect that whatever replaces it will be lousy, but I’ve grown a bit bored of the reruns.
I think the Roswell episode is my favorite:
“Oh, a lesson in not changing history from Mr. I’m-my-own-grandfather. Let’s get the hell out of here!”
One of my favorite exchanges in “WNFHGB”…
<Walter Koenig> When we woke up, we had these bodies…
<Fry> Say it in Russian!
<WK> (flatly and unenthusiastically) Ven ve voke up ve had dese…wodies
<Fry> (overjoyed) EEEEEEEEE!!!, now say “Nuclear Wessels”
<WK>No!
I think that Fry’s overjoyed “EEEE” is what sells that exchange, there’s just so much fannish joy and happiness in that utterance, it’s almost…Stimpy-ish in that regard 
another classic exchange…
Shatner and Leela are getting dressed after…well you know what’s implied here…, Fry and Nimoy walk from behind a boulder…
<Fry> We decided to work together…
<Nimoy>(cynically) yes, so have they…
Excellent episode, and also gave rise to another awesome quote: “Take that, causality!”
My favourite of all time, however, has to be Amazon Women in the Mood. Too many great Zapp lines.
“Ah, she’s built like a steakhouse, but she handles like a bistro!”
“You win again, gravity!”
The pickup lines.
The Shatner-esque karaoke.
“What are you, gay?”
And *Bea Arthur * as a guest voice? Lord have mercy, but that was awesome.
How can you forget “Death by Snoo-Snoo!”, “The spirit is willing but the flesh is weak” and Fry’s ambivalent series of double-takes when he finds out his fate?
Zap Brannigan kills me. That and Kifs reactions to his idiocy. It just doesn’t do him justice in writing. Their voices are what really sell the jokes to me.
ALL GLORY TO THE HYPNO-TOAD!
nitpick: “The spirit is willing but the flesh is bruised and spongy.”
And the Femputer’s shocked outrage when she’s told the men mocked women’s basketball:
“What! Did you explain that good fundamentals make up for the inablility to dunk?”
“welshey!!!”
Yeah, I’ve got that exasperated sigh of Kif’s down pat. I use it on my wife. It never fails to crack her up, especially if I follow it with the word “sexlexia”.
“Come, Kif, let’s eject. I found a children’s spacesuit you can wear.”
The sexiest disability.
Yeah, I love Futurama. Once, several years ago, my brother and I tried to follow the rules of the opening “title”…
“drink when you see the robot”
It ended well. Sort of. From what I am told. 
“Have you any idea what it’s like to be a fem-bot living in a man-bot man-puter’s world?”
“What?”
Of course, mere words can’t nail how utterly perfect Bender’s delivery is.
I think my favorite episode is the one with the alternate universe in the box. I can barely watch it because I’m constantly cracking up throughout the entire thing.
“So that’s why you said you had to meet that ghost!”
“You people and your slight differences disgust me!”
“Yes, it turns out the Bible is the real good news!”
Second might be the one with the Harlem Globetrotters and the time anomalies.
“I’m just glad my fat, ugly momma isn’t alive to see this.”
“Enough about your promiscuous mother, Hermes!”
100 cups of coffee. Brilliant!
