WARNING: If you couldn't tell from the title, this video contains graphic dry-erase marker images of male genetaila. If you think...even for a fleeting second...that you might be offended...do not watch this video! However, if you are...even remotely...as immature as I, you will probably be unable to stop laughing for the next five minutes. I'm ashamed of myself.

 

P.S. - I bet these people have an awesome marriage...and no kids.
