About this sound
This five-and-a-half-second clip is Stewie Griffin's high-pitched, scheming laugh from Family Guy, delivered in his clipped British accent as a plan clicks into place. It feels gleefully mischievous and a little sinister, like a toddler villain enjoying his own cleverness, and it works as an instant signal that something cheeky is about to happen.
