Since Duke Nukem was a horrible sexist, I'm absolutely shocked at anything he would have admired. I destroy the entire dry erase board with my flamethrower to make sure that doodle is completely erased.

I leave a collection of pet snakes to the next user.

This must be my lucky day, the collection of snakes turned out to be one single large snake with many heads. She told me that she was from Lerna and that Heracles was a liar. I always thought he's a strange dude...

I leave my collection of books about Greek mythology.

I have one Hera-va time perusing the old tomes.

I leave the next poster deep within a vast maze of one meter thick, six meter high walls and a solid rock foundation.

No problem, I've got a smartphone app for ecaping labyrinths (and yes, it all works, no matter how thick the walls, ain't technology great?) and easily find my way out. Some stupid mythological monster, half man, half bull, tries to attack me, but I just shoot it down with my trusty gun. You're history, monster!

I leave the head of that monster to the next user.

I put the head on my shield like Athena's aegis.

I leave the history textbook that tells the story above with a note "Those who don't study history are destined to repeat the history class."

v [glances at the book I wrote and leaves it for the next to post here]

*wonders why the author didn't bother to sign it, even though he stood right next to it*

I leave a pair of reading glasses (one strength fits all) and a bootle of Cardhu Whisky.

^ {gives you a shot glass full of whisky and a signed copy of the first printed edition of the history book that I wrote]
[fills three shot glasses with the whisky, one for me, one for the poster above me and leaves a shot of whisky for you, the next to post, along with a mysterious skeleton key and a treasure map]

^ I think that, "In spite of my age, I'm still just a brat in a rage." sounds more appropriate.

[smashes some pumpkins and passes the same goodies (the shot glass of whiskey, a mysterious skeleton key, and treasure map) on down again]

Uses map and skeleton key to find chest and opens it, only the person who is below knows what is in it and me unless told by the user below. Drinks the whiskey to quench my thirst after digging 50 feet in the ground.

passes the partly opened treasure chest down

In the chest is the still-beating heart of Davy Jones, which I stab to become the new Flying Dutchman captain. Unrelated, I also leave the next user an unopened can of Monster Energy.

I drink the can and, as could have been guessed from the name of the drink, I turn into a giant Godzilla-like monster which goes on to destroy several cities and countries. And since people know who's responsible for this tragic occurrence, MichaelD.965 becomes the most hated man on earth, with several bounties put on his head.

I leave the movie rights about my monstrous exploits to the next user.

With my new high-seas lifestyle, I evade all attempts on my life/freedom and film Morolf's biopic by having some of my crew stomp around Lego cities of my design. I upload the finished cut to every video-hosting site I can.

v [leaves a life-sized model of Godzilla made entirely of Lego building blocks]
