Guys this is highly recommended if you have some gut and work in an Office.
Bring 2 nerf guns to office. One Big one, and another single shot (or small) sidearm.
1) Disassemble/Unload the big one and conceal. (Disassembly/unloading not necessary, the big idea was just to give them a sense of dread while you prepped a scarier looking weapon).
2) Leave the sidearm loaded but not cocked next to you and work as usual. Put one or two spare darts nearby if you feel generous.

3) Wait for someone to come by and get tempted to try it out.
4) Teach them how to use it.
5) If they aim or shoot at you, bring out the other one.
6) Watch as co-worker panics.
Guns that will absolutely terrify your prey:
Rapid Fire - You may as well preload, prepump it and just bring the gun out in slow motion. Pre-pumping it depends on if you actually plan on firing it or not.
Longshot - Preload clip with ammo, but not in the longshot. May as well keep everything preassembled.
Recon - Preload clip with ammo, but not in the recon. Assemble the whole damn thing in front of them.
Vulcan - Whatever blunder you do with this thing, the sight of the Vulcan will still scare two shits out of anyone who just shot/aimed at you, so it doesn't matter. Bringing this to office is an entirely different story as well...
These tricks work more on people who have never seen larger dart guns before.
I've basically sent 3 separate people running to the opposite side of the office just assembling a Recon.
