Insane Troll Logic / Futurama

• From "How Hermes Requisitioned His Groove Back":
  Morgan Proctor: Why isn't this jacket in alphabetical order?
  Leela: What?!
  Morgan: The zipper. It should be at the bottom.
• And then there's this little saying:
  Fry: Thanks to denial, I'm immortal.
• Farnsworth has a nefarious habit of this as well. Given that he's Fry's descended nephew, it makes sense. To him, having his crew being sent on tedious and life-threatening suicide missions is "good news (everyone!)". When they are finally given a break at the beginning of "The Sting" by not having to go on the very mission that killed the previous Planet Express crew, Farnsworth tells them "Bad news, everyone! You're not good enough to go on our next mission!"
• The whole Waterfall family, implementing this with Hypocritical Humor.
  Waterfall Sr.: Now, now, no applause. Every time you clap your hands, you kill thousands of spores, which will someday form into nutritious fungus. Just show your appreciation with a mold-friendly thumbs-up.
  (Members of Penguins, Unlimited do so with awkward grins)
  Waterfall, Sr.: Please, hold your thumbs til the end.
• Zapp Brannigan can be so dumb, he even confuses himself with his troll logic. In "Brannigan, Begin Again", he accuses Leela of plotting to assassinate the Yarn People of Nylon 4 with giant novelty scissors, gloating that, "you forgot one thing: rock crushes scissors! But paper covers rock, and scissors cuts paper."
  Zapp: Kif, we have a conundrum! Search them for paper... and bring me a rock.
  Kif: Why?
• In "Bendless Love", Bender suspects girlfriend Anglelyne of harboring feelings for her ex, Flexo, a bending model robot that looks almost exactly like Bender. Bender disguises himself as Flexo and seduces Anglelyne using some decidedly un-Flexo-like moves, then reveals the ruse and angrily accuses her of loving Flexo so much that she even loves "anyone pretending to be him." She replies that maybe she just loves Bender so much that she'll love him no matter who he's pretending to be.
  Bender: Oh, how I wish I could believe or understand that!
