How did the moon get craters?

One day the Earth was lonely so it went out to get some crayons.  It came back and put a face on the moon but the moon started jabbering.  The Earth got tired of hearing the moon talking all the time so it grabbed its mountains and threw them at the moon.

 
How did the Earth get its atmosphere?

The moon smelled like rotten cheese.  The Earth couldn’t stand it anymore so it went out of its orbit and came back with air freshener.  It sprayed the air freshener around itself and that’s how it got its atmosphere.
