Don’t get on the floor, nobody walk the dinosaur

Anytime you go to open the door of your house or open the door of your car or the door of your refrigerator
 REMEMBER that it was ART that allowed that to happen!! 

Someone audibly having the thought to draw a door ; ("Oh, Pen the door")  
he was sitting in front of a building drawing it with a pen when he had the idea to draw the door. There were people walking into the building at the exact moment he exclaims to himself oh, pen the door. The person that was walking into the building literally at the exact same time heard him say it as his hand grasped the doorknob and it just stuck with Humanity forever Open the door.
I personally open doors everyday

The sentence "Open the door." Originated 400 years earlier When an artist had an Idea "Oh!, pen the door." out loud.
