I've used some of these, but there are some good variations that I haven't thought up yet!

I was surprised that my 5 year old knew that kids should never pick up a gun they find. In restaurants, she likes practicing her bread cutting skills with the rather dull serrated knives that those kinds of places have...freaks my wife out, but I try to teach to the moment.

And I think Kuovonne's idea of acting things out is excellent too...I'll have to add that to the old repertoire.
