Usher: It's your chance take her hand to the floor
(Fellas just the moment you've been waiting for)
Girl if you see something you like then let them know
(Ladies I know you’re ready)
Because you only got one chance
(Yeah yeah)
For your first dance
(You never forget about your first dance)
So take advantage of the slow jam
