Moonkeeper for a Day

If I was the moonkeeper for a day I would put a smiley face on the moon.

The Smiley face would have to be huge so that people can see it from miles away.

To make the face I would first put gun powder on the moon and then make the gun powder explode to make huge craters for the eyes and nose.

I would then drive for miles and miles in a bulldozer shifting sand from the surface of the moon to make the mouth.
