A frustrated wife... asked a marriage counselor how to get her husband's attention at bedtime. He said she should just do something different, and once she had his attention then nature would take its course.
So as an experiment that night, she put her nightgown on backwards to see if that would get his attention and start things moving along.
Husband: I see you have your nightgown on backward!
Wife: Aw, how nice that you noticed.
Husband: Of course I noticed! The brown stain is in the front!
