Rick Remender and I once got into it with an artist on the Image boards. He was making fun of our "smart comic books," and how we thought his early 90s Image stuff was silly. It turned into one of those old, massive, multi-page things that used to happen more than they do now.
At one point writer Seth Peck (who has worked with both Rick and me) made some funny, dry comments about the artist in question.
It ended with the artist writing a battle rap dissing us (a serious, non-ironic battle rap).
The battle rap was ridiculous, but the thing that makes me laugh most: A year later Jason Aaron, Jason Latour, Jeremy Haun, Tony Moore, Seth Peck and I set up our Atomic Revolver "studio" on MySpace, and sent out a bunch of invitations. The group photo we used was from a Halloween party. I was dressed as a fanboy, Jason A was a priest, Tony was the devil and Haun was Mage. Seth was a soldier, wearing a U.S. Army helmet.
The artist emailed a reply to our invite saying, "Sorry, I won't be your friend. That guy in the army hat made fun of me a lot."
For whatever reason, the fact that he referred to a helmet as an "army hat" still makes me laugh.
Anyway, that original thread went on forever and probably made it into the late, lamented Fanboy Rampage. I don't do that anymore.
