Dolls aren't just toys designed to look like lifeless, dead-eyed versions of the children who play with them, but also collectors' items that reflect the era they come from. Here's a list of the famous dolls that every collector should have in their glassed-in doll hutch:

• Mr. John, 1901: Victorian toymakers didn't want to create a female doll that girls might admire or model their bodies after, so they created Mr. John. The porcelain figure was dressed in a formal innkeeper’s tuxedo and had a real wooden cane he could swing at children.
  

• Stick Wearing Bird Nest, 1931: It looks like a woman if you pretend the nest is hair.
  

• Sally Wetsherself, 1961: Sally had a nozzle in her back that could be hooked up to a garden hose for what doll experts have called "the most realistic doll urination to date".
  

• USA Young Miss Dolls, 1974: Each doll in this series was from a different time period in American history and came infused with her own special guilt about American political policies.
  

• Nancy, 1986: Nancy was the youngest doll to ever get pregnant. She named her baby Arfie.
  

• Twerpz, 2002: Twerpz Dollz hate skool, luv candi, and eat their parents for breakfist!
