When I was ten, I went with my family to a Sam's Club in Fairbanks with a minifigure I had brought along for my entertainment. After about two hours, we had gotten what we needed/wanted from the shelves and what not, when we reached the cash register. But, because of the really large of stuff we had, it took a little while to sort through everything and then pay.
So, my parents did what any parent(s) would do: banish the noisy children to the Cafeteria/Food Court setup a good 40 or so feet away. After walking the aforementioned distance, my siblings and I (sister = Neko_IV (some have met via minecraft), younger brother isn't worth mentioning or calling a human) sat down at a lunch table. While waiting for our parents to finish up the purchasing our stuff, another kid (I would place him around 10-11 at the time) walked up to my table, in one of the few times we weren't biting my brother's head off or running around being annoying (hah, nothing changed, did it?).
He looked at me with a confident gaze and said, "Hey, I noticed that Exo-force Lego figure you had in hand when you walked in, and I thought I'd give you this." (Not actual quote) He removed from his pocket a yellow scimitar (LEGO, of course) and handed it to me. He walked off as I examined the weapon, and I gave it Hayato or whatever Exo-Force character it was I was playing with.
On an somewhat related topic, I nicked several heads, legs, bodies, fist fulls of legos, and some odd parts from school when I was a kid.
You must use only medieval pieces.
The Lego briks must have been manufactured between the 5th to the 15th century.
