A scene that's been ingratiated into pop culture is the Mac vs PC ads, which inspired the debate: Which is truly greater (obviously skewed towards Apple)? We don't really care about that particular debate, however it's inspired something so much greater:
Wolverine vs. Rorschach (or Watchmen vs. X-Men Origins: Wolverine)
Aligning all the conceptions that we have about the two makes for a hilarious display of each character's flaws as well as their strengths - including the line that made me laugh non-stop: "So does that mean both of our movies combined will cause people's skulls to cave in from sheer awesomeness?"
Anyway, check it out and envelop yourself with the, um, awesomeness.
