Happy half hour 

The time the bartenders give black people.

Bartender to black patrons- Since I am in a generous mood, I've decided to give you all one extra happy half hour, I will not cut you off early today.
White patron- You gave everyone else a full happy hour, how are they going to get happy in a half hour?
