Mark Ruffalo and Jon Stewart debate a Hulk vs. Superman fight

[hulu id=px1ltczlbjf83ovb-7qtgq width=512]

Jon Stewart loves asking stars about hypothetical superhero battles.

So when Mark Ruffalo stopped by the Daily Show to promote his new film Infinitely Polar Bear, Stewart asked him about one of his roles we're a little more familiar with — the Hulk.

So in a Hulk vs. Superman battle, who would win? Stewart comes out the gate with a pro-Superman stance, and Ruffalo gets mid-argument before telling Stewart, "I'll miss you."

As if we needed another reminder that August 6 was Stewart's last show. Way to kill the mood, Mark.
