Let's see here. I would buy a helicopter (not like I wasn't gonna buy one anyway), don a protective suit and a megaphone, have my pilot take me to just outside my office building, where I would shout at them through the megaphone to come out, listing the names of my least favourite coworkers mingled with various expletives. When they are outside or at least are staring out through open windows, I would call in the second helicopter (okay, this one may be somewhat wasteful) to come hang over my own. My ally up above would proceed to empty sackfuls of cow dung right into the propeller of my helicopter. If all goes to plan (I will be refining the plan to make it physically viable), my bosses and coworkers would be sprayed with the waste, and I would cry into my megaphone:

THE trout HAS HIT THE FAN! HAHAHAHAHAHAAAA! I QUIT!! SORRY RYAN, DIDN'T MEAN TO GET YOU ALL MESSY, WAS HOPING YOU WOULDN'T COME OUT - COME OVER FOR DRINKS IN MY NEW MANSION?! ALSO BOSS: I PISSED ON YOUR CAR! smurf YOU!!!

I would then shower them with dollar bills and pamphlets on everything I hate about them before moving out.
