This is a juicy one.

 These three women were roommates.
One night they all had all gone out
on dates and all came home at about the same time.

 The first one said, "You know you've been on a good date
when you come home with your hair all messed up."

 The second one said, "No, you know you've been on a good date
when you come home with your makeup all smeared."

 The third one said nothing, but reached under her skirt,
removed her panties and threw them against the wall,
where they stuck. then said,
 "Now THAT'S a good date!!"
