Thought I'd add this to the list of "humorous typo" threads.
As some of you may already know, I'm taking a math class this semester. We were supposed to have the notes for Unit 1 printed out today, but almost nobody did so the teacher had to hand out a sheet with today's notes on it. The title of the page was supposed to read "Unit 1 - Quadratic Functions", but the 'c' in 'functions' got left out so it actually read "Quadratic Fuctions". Probably nobody else will find this funny, but whatever, I'm posting it anyway.
