I don't remember which grade (maybe first), but I took one of those "half span bridge" wooden blocks, played with it and held it like a gun, and got in trouble.
Once in high school I brought a BB gun pistol to school, because really it's no big deal. No one got hurt (except for maybe a bird) and really no one knew.
Then when I was old enough I started buying real guns and now I am armed like an American civilian should be. GO LIBERTY!
