...and then someone would draw you doing all of that!!

... AND the picture you were drawing could be of you doing all of that... so someone could draw you drawing yourself drawing a cart and drawing water and drawing a gun while you drew yourself drawing a cart and drawing water and drawing a gun while you were in fact drawing water and a gun and a cart!!
I'm not 100% certain how much drawing is going on in there... mostly because of ALL OF THE RECURSION FOREVER!!
