Hulk vs. Superman - did they ever fight? Who won?
While this LOOKS like a Shark-vs-Gorilla, it is actually fully and eminently answerable... because there WERE comics in which Superman fought Hulk:
Fight #1: 1981 "DC and MARVEL present: #28: SUPERMAN and SPIDER-MAN".
That comic featured a fight between Hulk and Superman.
Hulk gets all hulked-out... but can't hurt or move Superman.
In the end, he's so exhausted, he converts back to Bruce Banner.
This clearly shows Superman winning.
Fight #2: 1996 "MARVEL COMIC vs DC #3: The showdow of the century".
It was a part of this special series: http://en.wikipedia.org/wiki/DC_vs._Marvel
Hulk vs Superman were one of the 5 fights which were decided by fan votes.
Superman made Hulk bleed from mouth and then knocked him out.
This clearly shows Superman winning.
Fight #3: 2001 "The Incredible Hulk vs. Superman". Play-by0
Hulk hits Superman pretty hard - knockdown.
Hulk throws Superman high up. No damage.
Superman flies fast and knocks Hulk away, through a bunch of rock. Knockdown.
Superman twirls Hulk, and throws him far far away
They fight some more, no damage.
Both are blasted from the sky with some rockets shot by presumably militarty. Both had wind knocked out of them.
Hulk throws a bunch of rockets at Superman.
All the while Superman tries to tell Hulk they were set up and shouldn't fight. While punching him, successfully :)
Then Hulk listened.
This one was more even handed but Superman has an edge as he hurt/knocked down/punched off Hulk more than vice versa.
