This is a short voice clip of Timmy asking "What the sigma?" in a puzzled, rising tone. It lasts just over a second, with the emphasis landing on the final word as if he has just seen something completely baffling. The delivery feels bewildered and amused at the same time, like a quick double-take you can hear, making it easy to picture the exact moment that prompted it.
