Cenedar's hate-feeding one was pretty good... as were several others I've missed... -ahem-
Lucario: 'Sup, Smashers? Name's Lucario, the coolest canine in Brawl.
Samus: Umm... what about W-
Lucario: His name is NOT to be spoken in my ultra-cool prescence... got that, n00b?
Lucario: Anyways, watch this, watch this.
Lucario: Pretty cool, right? Betcha no one ELSE can do that.
Link: Ummm... Samus can. So could Mewtwo.
Lucario: ...
Lucario: Shut up, and get out! You're ruining my intro!
Lucario: Where were we? Oh, yeah. I was just about to explain my Final Smash. It's a giant laser beam of ultimate destruction. Isn't that almost as ultra cool and unique as me?
Link: Umm.... Samus can do that, too.
Lucario: ...what did I just tell you?
SHUT
UP!
Ike: Don't worry, Link! I'll take care of him!
Lucario: Oh, you think you CAN, huh?
Bring it, punk!
Ike: Consider it... BROUGHT! Wait, where did he go?
Lucario: HA! TAKE THAT! THere's no WAY that someone else has a technique like that!
Link: Actually, that looks like a cross between Marth and Ike's Counter with Meta Knight's Dimensional Cape...
Lucario: Oh, that is IT! I've had it with you n00bs! But before I go...
I'm going to leave you with a little PRESENT! SAY GOODBYE TO SKYWORLD!
Link: Ack! My eyes!
Ike: My sword!
Pit: Noooo! My stage! My beautiful stage!
Lucario: Yeah, betcha wish you hadn't made fun of me now, huh?
