,
Actually Shin, I imagine it will go something like this:
SPIDER-MAN: Okay, people, my real name is Peter Parker. I know, I know, it's a real shock.
VULTURE: So you're some guy named Peter Parker. Big deal! I unmasked you weeks ago.
SANDMAN: I once unmasked him, although I didn’t get a good look at his face cause he ran away like a chicken.
INMATES AT THE RAFT: Hey, we unmasked him too! Only it was too dark to see.
SCORPION: Oh yeah?! I figured out who he was without unmasking him.
VENOM: Don’t make us laugh. On top of taking away our other, you we're told who he was. And you call yourself a private detective? Besides, we figured out Spider-Man was Parker long before any of you.
DOCTOR OCTOPUS: Correction. I had the distinct honor of being the very first to publicly unmask the meddlesome wall-crawler.
CAPTAIN STACY: You call what you did an unmasking? You only thought he was Peter Parker in disguise as Spider-Man and not that they were one and the same. I, on the other hand, used logic and detective work to figure it out.
BEN URICH: All I needed was my journalistic instincts.
DEBRA WHITMAN: Um...no offense, sir. But I figured out Peter was Spider-Man simply by following him up some stairs and finding Spider-Man on the roof instead.
HARRY OSBORN: Hey, lady. I figured out who he was simply by watching Spider-Man fight my dad. And I was even strung out on drugs at the time.
CHAMELEON: That's nothing, I learned who he really was and I was insane.
ROBOT PARENTS: You would have NEVER known had it not been for us. Peter told us he was Spider-Man outright.
BLACK CAT: Oh yeah?! I was the very first person who he willingly revealed his identity too. Of course, I can’t say I was thrilled when I found out, but...
TIM HARRISON: Sorry, toots. I was first. And all I had to do was ASK him.
BLACK CAT: That’s cause you were dying of cancer you stupid kid.
GWEN STACY: Actually, Peter once revealed who he was willingly my dad, Harry, MJ, and me.
BLACK CAT: Yeah, and from what I heard, you cried like a little girl and went bawling to daddy.
GWEN STACY: Shut up, you hussy!
BLACK CAT: Oh, that’s rich, coming from a girl who slept with the father of Peter’s best friend and refused to mention that she gave birth to twins.
SARAH: Hey, don’t you dare ridicule our mom that way.
GABRIEL: Yeah! Besides, we learned the truth after watching him jump over a wall to escape us.
AGENT MARIA HILL: Please. I used a psychic to figure out the truth.
MADAME WEB: Pish posh. I learned it through my own psychic powers before you did.
PROFESSOR X: Actually, that honor belongs to me.
DOCTOR STRANGE: No, Charles. I discovered his identity in the same manner long before you did.
DAREDEVIL: Well, I didn’t need psychic powers. I learned who he was by listening to his heart rhythms and voice patterns, as well as smelling his distinctive scent.
PUMA: All I needed smell, Hornhead.
WOLVERINE: I think ya came up a little short in that department, bub.
PUMA: Look who’s talking.
KA-ZAR: I’m afraid that I, Ka-Zar, lord of the Savage Land learned the truth in similar fashion long before then.
AUNT MAY: Goodness. All I did was walk in his room and found his costume lying on the floor.
BEN REILLY: Ha! I was BORN knowing that Peter and Spider-Man were one and the same, because I’m his clone.
KAINE: So did I, because I came before you did, Reilly!
JACKAL: Well, both of you wouldn’t have known if he hadn’t been for me, who learned the truth from a mere blood sample.
NICK FURY: We at S.H.I.E.L.D. already knew who he was long before any of you.
AGENT HILL: We did?
MORLUN: I simply learned simply through his totemistic essence.
SHATHRA THE SPIDER-WASP: As did I.
EZEKIEL: What am I, chopped liver?
THE GREAT WEAVER: And which none of you would’ve known without me.
IRON MAN: Wait a minute! None of you should count. Peter origins were a product of science, not intelligent design.
DOCTOR STRANGE: So you say.
CAPTAIN AMERICA: People, people. Let’s not get so upset. Besides, I figured out who he was...
NICK FURY: Only through accessing our files. As did ALL the Avengers.
BATMAN: I didn't even need computer files.
CAPTAIN AMERICA: What are you doing here? You don't belong in our universe?
BATMAN: Guess you forgot about DC vs. Marvel and JLA vs. Avengers, then.
THE SPECTRE: Which of course were the fault of those two brothers.
SUPERBOY PRIME: (whispering) Don't tell anybody, but it was actually me and one of my retcon punches.
J. JONAH JAMESON: Well, I knew it was Parker all along. That’s why I accepted all those pictures he took of himself. Wanted to help a young man get his feet wet, being the kind soul I am.
JOE ROBERTSON: So I guess that whole incident with you thinking that your own son was Spider-Man was just act, considering how they were seen together numerous times.
JAMESON: Oh, and I suppose you knew all along, eh smarty pants?
ROBERTSON: Maybe....
GREEN GOBLIN: Oh please. All of those attempts are pathetic compared to what I’ve accomplished. Why, I was the very first person to learn Spider-Man was really Peter Parker. And that’s more than any of you have ever done.
MARY JANE: Sorry, Norman. I was the very first person to ever learn the truth, and I’ve known who he was the very night his Uncle Ben died. So there. (Sticks out tongue)
THE WATCHER: Actually, it was I, the Watcher, who sees all things and all possibilities. I have known that the one you call Spider-Man was Peter Parker long before he ever became Spider-Man.
STAN LEE: Actually, it was me, since I was the one who created Spidey.
STEVE DITKO: No, it was me.
STAN LEE: Steve, let’s not start THAT again.
GOD: Don’t I get a say in this?
BRAIN MICHEAL BENDIS: Good thing they're not talking about the Ultimate universe.
