Salt-N-Pepa's here, and we're in effect
Want you to push it, babe
Who's in my day bed and night
Workin' up a sweat?

The story:

Always thought they just meant to say, "Who's in my bed day and night," but mixed up the words 'bed' and 'day.' Then I thought maybe they said, "Who's in my daybed at night." Finally looked it up today and was kinda disappointed. Cummon, Pepa baby, you know you like it in the daybed.
