I don’t have labs anymore because I’m in math but I remember back in 1st yr I had a physics course. I showed up late on the 1st day of the lab & was stuck with some old(er) guy who wore his spandex shorts & smelled like BO all the time. But he had a good mnemonic for the colour-coding of resistors: “black boys rape our young white girls but violet gives willingly.” (black=black, boys=blue, rape=red, our=orange, etc)
