Funny / Sinestro Corps War

• Guy Gardner taunting the captive Superboy-Prime.
  Guy: Hope you're havin' fun in there kid. My ass sends it's love.
  • All the while he is creating an energy construct in the shape of Supergirl, in all her Ms. Fanservice glory.
• Hal Jordan and John Stewart's mid-battle banter about the outfit Guy wore during the brief time he used Sinestro's original ring.
  Hal: Do you... remember that big "G" he wore on his jacket?
  John: Do you remember what Guy said it stood for?
  Hal: "Girl-magnet."
• Geoff Johns was actually able to work in a joke made in The Simpsons Movie that "EPA" was a sound effect made in Green Lantern #25 when Sinestro threw Hal Jordan into a vat of acid. In the actual issue #25, one of the final issues of the crossover, there is indeed an "eee-pa!" sound effect during a battle between Hal and Sinestro. (No vat of acid, unfortunately.)
