Little Johnny comes home from school with a note from his teacher,
 indicating that "Johnny seems to be having some difficulty with
 the differences between boys and girls," and would his mother
 "...please sit down and have a talk with Johnny about this."
 
 So, Johnny's mother takes him quietly by the hand upstairs to her
 bedroom, and closes the door.
 
 "First Johnny, I want you to take off my blouse..." So he
 unbuttons her blouse and takes it off.
 
 "OK, now take off my skirt..." And he takes off her skirt.
 
 "Now, take off my bra..." Which he does.
 
 "And now, Johnny, please take off my panties..."
 
 And when Johnny finishes removing these, she says,
 
 "Johnny, PLEASE don't wear any of my clothes to school any more!
