ArchPundit

Otter: Ladies and gentlemen, I’ll be brief. The issue here is not whether we broke a few rules, or took a few liberties with our female party guests – we did.
[winks at Dean Wormer]
Otter: But you can’t hold a whole fraternity responsible for the behavior of a few, sick twisted individuals. For if you do, then shouldn’t we blame the whole fraternity system? And if the whole fraternity system is guilty, then isn’t this an indictment of our educational institutions in general? I put it to you, Greg – isn’t this an indictment of our entire American society? Well, you can do whatever you want to us, but we’re not going to sit here and listen to you badmouth the United States of America. Gentlemen!
[Leads the Deltas out of the hearing, all humming the Star-Spangled Banner]

Add this to his Pearl Harbor claims and we now know he is either Otter or Bluto:

D-Day: War’s over, man. Wormer dropped the big one.
Bluto: Over? Did you say “over”? Nothing is over until we decide it is! Was it over when the Germans bombed Pearl Harbor? Hell no!
Otter: Germans?
Boon: Forget it, he’s rolling.
Bluto: And it ain’t over now. ‘Cause when the goin’ gets tough…
[thinks hard]
Bluto: the tough get goin’! Who’s with me? Let’s go!
[runs out, alone; then returns]
Bluto: What the fuck happened to the Delta I used to know? Where’s the spirit? Where’s the guts, huh? This could be the greatest night of our lives, but you’re gonna let it be the worst. “Ooh, we’re afraid to go with you Bluto, we might get in trouble.” Well just kiss my ass from now on! Not me! I’m not gonna take this. Wormer, he’s a dead man! Marmalard, dead! Niedermeyer…
Otter: Dead! Bluto’s right. Psychotic, but absolutely right. We gotta take these bastards. Now we could do it with conventional weapons that could take years and cost millions of lives. No, I think we have to go all out. I think that this situation absolutely requires a really futile and stupid gesture be done on somebody’s part.
Bluto: We’re just the guys to do it.
D-Day: Let’s do it.
Bluto: *Let’s do it*!
