^ That episode is gold.  One of my favourites:
Fry: Okay, you're on a date. What's the first thing you do?  
  
Dr. Zoidberg: Ask her to mate with me.  
  
Fry: No, tell her she's special.  
  
Dr. Zoidberg: But she's not, she's merely the female with the largest clutch of eggs.  
  
Fry: Well, tell her that. And then what?  
  
Dr. Zoidberg: Then mating.  
  
Fry: No, make up some feelings and tell her you have them.  
 [
Dr. Zoidberg raises his hand]  
  
Fry: Yes?  
  
Dr. Zoidberg: Is desire to mate a feeling?  
  
Fry: Ugh, you're not even trying.  
  
Dr. Zoidberg: Ohhh, it's all so complicated, with the flowers, and the romance, and the lies upon lies. 
Professor Hubert Farnsworth: You must take him to his ancient home world, which will soon erupt in an orgy of invertebrate sex.  
  
Fry: Oh baby. I'm THERE.  
  
Leela: Fry, do you even understand the word "invertebrate"?  
  
Fry: Nope, but that's not the word I'm interested in.
