"Nice white kids
Who like to lead the way
And once a month
We have our "negro day!"-- from The Nicest Kids in Town
Motormouth Maybelle is DJ for the event, which Velma von Tussle says caters toward laundresses and maids. Tracy loves the dances shown by Seaweed and the Dynamites, and wishes that "every day could be Negro Day!".
It is shown during "The New Girl in Town" when the Dynamites are doing Rhythm and Blues on a Thursday, and there is an ad for a hair relaxer.
Later in Hairspray, it gets cancelled, when the show gets integrated.
