Place it at the start of a paradox sequence, then cut to the confusing footage and finish with Law & Order Dun Dun for the reveal, or follow it with Windows XP Error Sound when the timeline completely breaks down.
About this sound
This 2.5-second clip features David Tennant as the Tenth Doctor cheerfully explaining time travel with the rhyming phrase wibbly wobbly, timey wimey, delivered in a bright, rolling voice that turns a tangled idea into a joke. It feels warm, clever and gleefully confusing, like a knowing wink when logic breaks down. The line comes from the 2007 Doctor Who episode Blink.
