Put it at the cut where a scene jumps to another year, then follow it with the Law and Order Dun Dun to mark the reveal. For a fast montage of changing dates and timelines, layer the Cartoon Chase Music underneath and let this clip introduce each new jump.
About this sound
This short spoken clip delivers the famous Doctor Who phrase about time being wibbly-wobbly and timey-whimey in just over two seconds. The playful, slightly bewildered delivery makes tangled timelines feel funny rather than confusing. It comes from Doctor Who, where the Doctor uses the nonsense words to explain how time really works.
