What's the dumbest thing anyone in you school class/work etc. Every said or asked?

Example; I was in my 9th grade science class and we were talking about modifying genes, like mutations and stuff and one girls speaks up " I dont see why this would be so difficult, I change genes all the time" and were all like wat. The teacher says no she doesn't, but she's all " everyday, unless I wear shorts" and the teacher is just like "blue jeans, not genes. Omfg"

edit: spelling in title
