When I was younger, I used to watch music videos, which were typically just spliced together concert footage. Eventually I saw one with a story and they had a dramatic shot where the lyrics kept going but the singer stopped singing, and then for a while I was convinced that singers had to be ventriloquists and they only moved their mouths to help everyone else learn the words, too. Then I saw a video where there were a bunch of jump cuts where the singer had on different outfits (so the singer was in a new outfit every two seconds but you never saw them change). That one had me stumped for weeks.
