The 5 best toys of all time

The vast majority of the time I do the toy reviews on this site.  I really enjoy reviewing toys, and Li'l Girlie enjoys playing with them, so that works out well for us.  This time, though, I've gotta hand it to Geek Dad on Wired.  He's written a wonderful compilation of the 5 best toys of all time;  I couldn't have done it better.

Not many toys can come close to the amount of imagination these toys can inspire, and most are readily available in wide areas of the world.  Whatever culture or economic group you are in, it's highly likely that your kid will play with one of these toys whenever the opportunity arises.  (Right now, my daughter is really into toy #1 and toy #5)  That's her in the bike helmet -- it's like her security blanket, except it's a helmet. 

As an added bonus, each of the top 5 is relatively inexpensive and/or can be obtained for free.  That's my favorite price. 

Which of the top 5 toys does your child play with?  Were there any surprises about which ones made the cut?
