Bruno Mars sings about wanting to spontaneously marry his partner on a night when they are looking for something fun to do. He suggests going to a little chapel and getting married without anyone knowing. He says it doesn't matter if they are drunk, they have cash and can party. He tells her not to say no and to just say yes, so they can go have fun. He will get a ring and they can run off and get married, and if in the morning she wants to break up that's fine. In the end, he asks her directly if she will marry him.
