I will fucking kill you
Your dead at recess, Jason.
I read more webcomics than any other carbon based life-form. I know I've read all the comics you have. This joke was my idea. Hell Jason, Jenn and I have been saying these lines for like four months before I finally got around to making it into a comic! If someone else wrote a similar joke before me, I don't know about it. Thus if it has been done before I seriously doubt it was in a webcomic.
