It is bleach day. Ashley usually has blue hair and Aussie, purple. Pretty entertaining. Anyway, to keep it looking right, they bleach it once in a while and recolor. October 11 was that day.
They decided to switch places for some pictures. Aussie became Ashley with her mannerisms. Ashley became Aussie. The top picture is right, then they switched shirts and glasses. If that wasn't good enough, they mimicked each other's mannerisms with Aussie doing Ashley's 'peace' sign and Ashley grasping a Rubik's Cube.
