Boys and blocks

We have had the wooden blocks out in the living room for the past several days.  It kind of drives me crazy, but there isn't enough room in the bedrooms to play, and they have been playing so nicely (for the most part) that I have left them out.
Here are their latest creations.  Dr. D made a "52 Bomber".  It drops a million bombs at once, and when one hits a bad guy it turns them into a good guy.

Here is his garage also.  They have been keeping cars in it.

Here is Tail Gunner and his firetruck creation.  It's a firetruck with a block on top.  :)

Blocks are one of my favorite toys.  What are your favorite toys?
