Ha! We live right by a dam on the Mississippi, and I was joking about the lock set-up on it. Told my 8yr old that the dam owner had a dam key for the dam lock and whenever he wanted to open up the dam thing, he would use his dam key. There is a trolley that goes over it, so we talked about the dam trolley and having to walk up the dam steps to it...
Funny, till 3 days later, the class she is in, at a catholic school, had a discussion about the dam, and she repeated me, word for word... I heard a little crap about that.
