Fly Me to the Moon began as a song written by Bart Howard in 1954 and became widely known through Frank Sinatra's 1964 recording, whose smooth swing made it a lasting standard about travelling to the moon and beyond. Short excerpts have since circulated widely online as meme and reaction sounds, where the familiar melody is recognised instantly even out of context. Pairing it with a shark adds an unexpected, playful contrast, which is why brief clips like this one keep appearing in short videos, edits and social posts.
