Today I’d like to have a very serious talk about… a toy. Yes, very serious toy. Most of people I am sure have seen it. You can google it under the name Roly-Poly Doll or Roly-Poly Toy, or under Tumbler Doll. In Russian it is very well know under the name Nevolyashka or Vanka-Vstanka. There are similar dolls in other countries. They look different, but they all have a similar feature: no matter how many times you knock them down, no matter how you throw them on the floor, they always get up.
