Although not an uncomprehending baby, I felt I HAD to include this as it happened only 2 days ago with my EIGHT year old DD.
We often muck about pretending to ring people to grass the other up for doing something, eg. once when I swore about my Dad, she pretended to ring him and tell him what I'd said...
The other day, she 'signed' my name on a 'letter' she had written during a game. I told her it's illegal to forge someone else's signature and pretended to ring the police. She was laughing throughout my pretend phonecall, knowing I was messing about, and then burst into tears when I hung up the phone suddenly thinking I had really done it. Oh the shame! I had to go into my call register and prove I hadn't ACTUALLY dialled 999, LOL Bless her, she was quite worried they were coming for her! Never doing that again.
This thread is absolutely hilarious, I've nearly PMSL several times reading it, and I have done some of the things mentioned too, thank god it's not just me!!
