First lab of second year electrical physics. The instructions are to draw lines of various lengths with graphite pencils, plot the resistance vs length, and calculate the resistivity.

Everyone starts laughing about how easy this shit is going to be. We know from the textbook that our graph should be linear, but when we measure the resistances of the lines our results are all over the fucking place. A 10cm line is 700 ohms, an 11cm line is 412 ohms, a 13 cm line is 3091 ohms, etc.

Most people decide to make up answers so they can draw a nice linear graph. They think that's what the prof wants to see , so they will lose marks otherwise.

Prof hands back the labs. Everyone with a nice linear graph gets a zero, people with shitty looking data get full marks. "If anyone thinks I may have made a marking mistake please see me in my office after class". Everyone who showed up to his office got royally chewed out for being a dishonest piece of shit. He knew the experiment would produce chaotic results. He was testing our integrity.
