9+10=21
Meme · 6.2s · 1,800 plays
'What's nine plus ten?' 'Twenty-one.' The most famous incorrect arithmetic in internet history, and a founding text of Vine comedy. The confidence of the delivery is what immortalised it — the kid never wavered, never corrected, and accidentally created a decade-long meme. Still funny. Still wrong. Still twenty-one.
Origin: From the legendary 2013 Vine — the internet's favourite wrong answer.
