mine are (or the ones I can think of):

tip over the tray on the high chair (but I guess a lot of kids do that.). I hated my high chair soooo much.

- throw my marble collection at vases or other breakable objects, then laugh when they smashed

-peeing in telephone boxes (which sort of became an obsession)

that's all I can think of for now.. their's probbaly others too- I'll think on it.

what about you?
