The Dante thing wasn't the main joke (
This is Dante).
The joke is that he's supposed to be a member of the Archer class, but he fights with dual scimitars instead of a bow. (much to the confusion of the other characters).
I picture it as going something like this:
[spoiler]
DM: Okay, and Player 2 is an Archer.
Player 2: There isn't any archer class.
Others: *sigh*
Player 1: Weren't you paying attention? There isn't exactly a "Saber" class either.
DM: Just build a ranger.
Player 2: Okay, see you guys next week!
DM: What... What is that.
Player 2: It's my archer!
Player 3: Um, did you get that picture from Devil M-
DM: Why is he dual-wielding swords?
Player 2: You said to build a ranger!
DM: ...
DM: When I said "Archer", did that not tip you off to the appropriate combat style?
Player 3: Look, can we just get this thing started?
DM: *sigh* All right. Rin watches as the completed magic circle begins to glow. Then-
Player 2: BOOM!
DM: ...then there is a flash of light and an... an
Archer-class Servant appears before you.
Player 2: "Hey there, baby! Whassup?"DM: Berserker roars and strikes with his club, but misses, striking the floor and shattering it.
Player 2: Ouch! I'm getting out of here!
DM: As Berserker turns and follows you, he trips over a piece of rubble. As he struggles to regain his balance he is temporarily unable to defend himse-
Player 2: I hit him with my swords!
DM: You can't do that, you're too far away.
Player 2: Aw man, I guess I don't have any options then.
DM: *cough* You got a bow in your starting package, even if you never. freaking. used it.
Player 2: Okay, then I use my bow to fire-
DM: Alright. *takes out dice*
Player 2: -a sword at him.
DM: ...
Player 1: ...
Player 3: ...
Player 2: DM: Oh, too late, he manages to regain his balance in time to block the attack.Player 2: This bow sucks, I'm making a run for it!
Player 1: You ****ing idiot, you're supposed to be keeping them away from us.
DM: Berserker follows-
Player 2: I make a ranged attack. But that bow sucks, so I'll throw my swords at him instead.
DM: You miss.
Player 2: Okay, I use flurry and throw
four swords at him this time.
DM: Wait, you can't... *checks character sheer* Okay, why do you have that many swords?
Player 2: In case I lose my pack!
DM: Berserker is still standing. He charges you and attacks. *rolls* It's a critical hit.
Player 2: Crap. How many hit points do I have left?
DM: Two.
Player 2: Okay, time to bring out the big guns. I draw my scroll of
miracle...
DM: You
do not have a scroll of miracle.
Player 2: It says it right here on my sheet!
DM: You just wrote that in now! Okay, screw this. Rocks fall, everybody dies.
Player 2: But-
DM: ROCKS FALL, EVERYBODY DIES!
Player 3: Wait a minute, what about us?
DM: Okay, sorry, just "Archer" dies.
Player 2: Aw, c'mon guys, can't you let me back in?
DM: ...I am giving you one more chance. You can take over Shirou.
Player 2: Sweet!
Player 1: Wait, he's going to be playing my character's Master?
DM: Deal with it. Just remember, this is a different character. Don't go playing him the same way as your last one.
Player 2: What, do you think I'm an idiot?
Player 2: "Hey there, baby! Whassup?"[/spoiler]
