Question of the Day: Build

Have you ever built anything?

Answers I've received so far:
~ Forts
~ An airplane for my brother, but I gave it to my Dad.
~ Yeah, but out of Legos: houses, a penis, a space ship, and maybe a gas station, too.
~ I pitched a tent once!

(P.S. I do not make up these answers!)

My answer:
The first two things that come to mind are a hutch for my pet rabbits when I was in middle school and a desk last month (though that was less involved than it sounds).
