Anyone else look at this picture and start singing the Discovery Channel song or is it just me?

Moon illusion, the moon always seems larger in angular size when it is near the horizon than when it is high in the sky. In addition the moon does vary in angular size due to the eccentricity of its orbit. When the moon is closest to earth it obviously appears larger.
