This rivalry reeks of politics, so I'm putting it here to punish you.

Duke Nukem is a popular FPS video game character who kills space aliens, mutants, and is mean to everyone in the process. In Duke Nukem 3d, several of Duke's one-liners come from characters played by Bruce Campbell.

The problem:  Campbell thinks Duke's writers are unoriginal rip-off artists. Campbell fans attack Duke fans.

From a fan's perspective, Duke's attitude (and one of his weapons) reflects some of Campbell's, and this game has many parodies on hollywood like Star Wars, Aliens, etc. Some Duke fans believe Duke's quoting of Campbell and Piper was respectful. Duke fans eat this stuff up. So what happens when Duke fans hear where Duke's lines came from? I watched Army of Darkness like three times.

Mistake #1:  Campbell never played Duke Nukem yet has an opinion about it. Congratulations, Bruce, now everyone knows you're an impressionable idiot. Hail to the king, baby!

Mistake #2:  Campbell took a confrontational posture about possible legal action. Isn't the world full of enough morons who are ready to fight as soon as they have a bad impression of someone? Let me repeat that; if you assume there is a gremlin, there's a good chance you'll find one.

Mistake #3:  Campbell fans act like Megadeth fans right after Metallica stole The Four Horsemen from Mechanix. There's only one major difference: Campbell fans and Metallica fans deliver pizza and pick up the trash for Megadeth fans. Actually, Dave Mustaine did have a problem with others biting his style, but they lost their teeth and got carpal tunnel. So Dave is happy.

And now, kids, let's learn today's two lessons.

1.  In a celebrity deathmatch between Duke Nukem and Campbell, the winner would be Maddox.
2.  The way to keep fans is by stirring up less controversy than a politician.
