Remember when you could smoke in the workplace? Some new hires sure do.
This is a nasty one we used to pull on new hires years ago.
Back in the days when smoking was allowed in the workplace we would run a tube from an adjacent workstation to the inside of an oscilloscope.We would task the new hire with making a simple measurement using the scope.
We would wait until the new hire was hard at it and then one of the smokers in the lab would blow cigarette smoke through the tube.
You can imagine the new hires horror his first day on the job when he saw smoke pouring out of an oscilloscope he was working on.
