In the new Avengers Vs X-Men #1 comic, Spider-Man creates a prodigious amount of webbing to save people falling from the sky. He makes a quip, as he is want to do:
Aaaand you're welcome.
Those are official Spider-Man spider-webs, by the way.
Not sold in stores.
In the mean time Ms Marvel is catching the tip of the Empire State Building, Iron Man is vapourising an airplane wing and Thor is catching a failing plane in a hurricane he just created.
It got me thinking, has Spider-Man ever made a quip that wasted time in such a way that lost someone their life?
