Bathroom Sign Out

So I know pretty much every teacher has a "Bathroom Sign Out" that they use to keep track of which kids are going to the restroom.  I just wanted to post this because I thought the comic was hilarious.  I wonder if my students will get it... lol

 and then there's just the actual sign out page.  I used to have just a notebook, but I never could keep up with it...so I figured pre-typed pages worked better than just the notebook!
