It'll probably be some sort of pun. Like, if I got stabbed, I'd say something like, "You make a very good POINT." If I get shot, "Dude, that just BLEW ME AWAY." Etc.
I'd say a pun, and when my friends hear those were my last words, they'd be all OMG SRSLY?!?!
Or it'd be something like, "Oh hell, my friends are going to think this is just freakin' HILARIOUS."
