I have, but when I was pretty young, no older than 7 I'd say.
I've done some similar things like that, though. Once a long time ago I was calling someone's house to see if my brother was there. When they said "No, he's not", I automatically said "Can I take a message?", because I was so used to saying that when other people called. When I realised that I was the one who called THEM in the first place, I got really embarrased and hung up.
