Charlie Bit My Finger was uploaded to YouTube in 2007 as a home video of British brothers Harry and Charlie Davies-Carr, and it became one of the platform's earliest viral hits, viewed hundreds of millions of times. In the clip, baby Charlie bites Harry's finger, prompting Harry's pained complaint that viewers quoted for years. The moment spread through reaction videos, remixes and short-form edits, and it still works today because the sound is instantly recognisable, short and tied to a shared internet memory.
