Before everyone was on the Internet; before everyone recorded everything; and before she would get absolutely in trouble, I had a 7th grade math teacher with a shirt that had the quadratic formula across the chest area.
One day when teaching this topic, she wore a jacket over it and when introducing the formula, she unzips the jacket and with great enthusiasm, reveals her formula to the whole class. To this day I have that formula hardcoded into my brain and, on occasion, use it (mostly on bullshit employment tests but still.)
