I am currently working on a swimming training SaaS and was in the middle of implementing technique drill videos think short clips for specific drills cues and common mistakes
While wiring everything up I asked Claude Code to just drop in a placeholder video so I could finish the layout states and interactions first Nothing fancy just something temporary until the real content is ready
Claude Code decided that the most appropriate placeholder was Rick Astley
Not a random video...
Not a grey box..
Not sample mp4....
A full on Rickroll
Which means the app now politely teaches swimming technique while silently promising to never give you up

This made my day. Claude Code has a great sense of humor.
I'm guessing its not a coincidence and the url for that video is among the highest most shared links in content from the training data.
Love this song aswell. First time I saw it was at the corner store
AI used to to use DEVELOPERS DEVELOPERS DEVELOPERS video when using the API 😂 but I guess nowadays that wouldn’t be accurate
I can wholeheartedly say I've been rickrolled by Claude Code many, many many times. And if you call it out for it, it will actually lol at you.
