[Stallone murders a bad guy.]
Stallone sidekick (aghast): "You don't just kill a guy like that!"
Stallone (satisfied): "I just did."
This type of scene is ubiquitous in the Stallone canon; either a nobody supporting character serves up an alley-oop that Stallone confidently finishes (not unlike the above exchange) or Stallone delivers the gold by himself. Either way, we're all winners.
With so many cheesy lines, it was tough to choose just ten. But someone had to do it.
(Special thanks to this video for most of the material, even though its midpoint is unfortunately a creepy shot of Stallone's character in "Spy Kids 3D.")
