So apparently Marvel pitched a crossover with WCW in 2000 that would have various Marvel superheroes vs.various WCW wrestlers. We would have gotten Spider-Man vs. Sting, Bret Hart vs. Captain America, and of course Hogan vs. Hulk. There's even artwork featuring Bret putting Captain America in the sharpshooter. It was WCW that turned it down because even they thought it was dumb. It's number 3 on this list.
What's really bonkers is that Cracked is still around.
