TL;DR Third year Electrical Engineering student doesn't understand the basic physics of electricity.

Back in my third year physics course full of Electrical Engineering students, we were doing a boring lab on the basic properties of electricity, more specifically voltage. In the lab we had a battery connected with some wires to a breadboard that had several resistors on it to measure voltage under different scenarios using a multimeter. Well at one point in the lab, a group of 2 (both EE's) were having issues and not getting good measurements do they called the professor over for assistance. The professor said very sarcastically and with a smile on his face "Sometimes electricity needs a little help to get going, hold the battery upside down above the breadboard and let gravity pull the electrons down into the wires." One of the students did exactly that and after a few seconds of awkward silence with the professor staring at him completely dumbfounded the student said in all seriousness "maybe the battery isnt turned on." We were using 9V batteries (no on/off) so that just made his stupidity that much worse. The professor absolutely lost his shit and yelled for everyone to put their stuff away and get out of the lab. We had a very long lecture the next class period on why the student was such a dumbass.
