An axe. Yeap, just and axe. Axe's fix everything.

A belt-fed shotgun with mix-and-match ammunition types and an armored hazmat suit. I'm also keeping the sledgehammer needed to break it.

Yep, the world energy crisis will be saved by gun violence.

psh, the world energy crisis?? hah, I'm talking about the angry radioactive monsters that would be coming my way after the fallout! I'm saving ME ^_^

All the scienists? Each and every one of them? Plus all businessmen? Congratulations, you've prevented stem-cell research and plunged humanity into the Dark Ages. Again.

YEAH! GO TEAM VISIGOTH!

You know, I think a super-flu would be better than measly old can of pheromones. If the world doesn't dance to the tune of the man holding a vial of Capt. Tripps, then that's no kind of world I'd like to live in.

Um... Duh?
Duct tape.

A hammer to break the emergency glass with. (Duuuuh!?)

I'd store a secret Nazi Raygun. If I've learned anything from games, comics, and other sources of information about the future, it's that Nazi super science beats modern and future tech nine times out of ten.

Disclaimer: I am in no way associated with Nazi Super Science, my work is generic and perfectly harmless to synthetic life forms.

I should be pretty worried then, because I'm a real boy! I wished on a star and everything!

A towel, A pointy stick and gordon freeman

A Blue Police Box.

Why deal with the future when you can skip past the bad parts.

Bad idea. Gordon will use the pointy stick to bash his way out of the glass. He brought down an inter-dimensional empire with his crowbar, can you imagine what he'd do to you?

But what if you coax him into joining you? Then with nothing bar a stick and a towel you would rule the world!

toilet paper, lots and lots of toilet paper.
or, a time machine and the portal gun- fire an orange portal into a black hole, then a blue one onto the ground and high-tail it out of there...
or, you know, just toilet paper.
or better yet some oil. I'd be rich.

Okay, well, clearly it wouldn't kill all the scientists. Just those with ill-intent in their hearts.

In fact, maybe we should refine it to be a plague that would kill off anyone who was power-hungry or extremely greedy.
