Coat the handle of the walk-in cooler with jalapeno juice, and get one of your co-workers that you don't like to open the door. When he grabs the handle, sneak up behind him and slit his throat...

1. Pranks have no place in a hazardous workplace.

3. and yet...

working in a few kitchens, they all seem to run on pranks, usually ones that end with someone bleeding or burnt.

2. That's just as nifty as the one about getting a co-worker to fall down an empty elevator shaft

5. I realize not everybody is a fan, but this seems to waste jalapeños. And it's wrong to waste food.

You might also check whether your state laws allow you to waste co-workers
