I am embarrissed now, but when I was younger, our dog had run up the garden path and my aunty was not too far away, so I went to play a prank. I kept my lips still and called my aunt by her name pretending that it was the dog. An innocent prank in itself but it worked too well. The dog looked at them as if she had said it, and when my Dad (Who had heard it) came and asked me, I denied it... I actually denied it because I would have been told off for saying my aunts name without calling her aunty... So right to the day my Dad passed away, he thought the dog had called out my aunts name all those years ago! Oops!
