A/N: Ok, so this is my first attempt at something like this, not exactly sure how it's going to turn out. Thanks go to sick-atxxheart for creating this challenge and giving me some inspiration. I'm not gonna bug you guys with an author's note at the end of every chapter asking for reviews, so I'll just say it now: please let me know what you think! Hope you enjoy, and let's get on with the show.

The first time he laughed was when he was just 3 weeks old.

Only his mum had been there, and nobody believed her when she told them afterwards, but it didn't matter. She knew what she had heard.

She had been standing in front of his crib, trying to kill the spider scuttling across the wall of their living room. Desperate not to scream hysterically, she shot a stunning spell at the hideous creature, only to have it rebound off a picture frame and hit her square in the face.

But, despite the fact that she was slightly...stupified, she had heard him.

Her three-week-old son had laughed.

Looking back, she should have realised then that "prankster" was simply something in his genes.
