A black moment
When you forget what day it is, but 'Friday' starts playing in your head and you're either happy or furious.
I was on the bus and suddenly I was screaming 'I love you, I love you, I love you!'
I started singing 'I love you, I love you, I love you' at work and my boss yelled at me.
I was in the middle of a math test and started singing 'Friday' like it was a national anthem.
