Why do we buy toys?

I am not sure that these pictures are really going to need much of an explanation. Just wondering why, as parents, we spend so much hard-earned $$$ on toys that the kids break within 24 hours. What they really lurve to play with are all non-toy items in the house. Below are such examples...

The Fan...
My bra...
My cutting mat...
The hamper...
Theme song for today is my favorite song from a movie all about toys- "You've Got A Friend In Me" from Toy Story.
