Pharrell Williams' Happy has been widely used for memes on the internet since it first came out back in June 2013. The song is also featured in the billion views list on YouTube, amassing over 1.2 billion views in a decade.

Moving forward to 2023, as TikTok is famous for bringing back old music and make it go big again, user @dduck_.gach40ffica1 uploaded a slowed + reverb version of "Happy" in early November 2023, which quickly inspired a new trend on the platform that garnered over 100,000 videos featured. TikTokers have now repurposed the initial verse of the song, "It might seem crazy what I'm 'bout to say," using the phrase to express absurd and memorable character quotes or real historical events. Check out 20 hilarious images from Pharrell's "Happy" TikTok trend.
