I do try to limit the quotes to those I've encountered while reading something, or something that I've remembered being told by a parent/coach/mentor, as opposed to just grabbing a quote image and pasting it in. YMMV.
"Katy, bar the door!" was an expression used by my old football coach, Roger Hibbs, when a play went well or a defensive push really messed things up at practice. He passed away earlier this year, a good man, and every time I see that saying I think of him.
