I do NOT want to know what would happen otherwise...

At the basement of a building with 5 floors, Adam, Bob, Cindy, Diana and Edward entered the elevator. The elevator goes only up and doesn’t come back, and each person gets out of the elevator at one of the five floors. In how many ways can the five people leave the elevator in such a way that at no time are there a male and a female alone in the elevator?


Did anybody get the joke in the title? :D
