# What Dinosaur Has 500 Teeth?
"What Dinosaur Has 500 Teeth?", also framed as "Don't Google Which Dinosaur Had 500 Teeth," is a Reddit bait joke from September 2019 that warns readers away from the dinosaur Nigersaurus because its scientific name sounds close to a racial slur. Anti-comedy subreddit posts spread the warning widely in late December 2019, and by January 2020 The Sun was covering the stunt as a racist prank campaign.
## Origin
A /r/teenagers user posted the earliest known warning against Googling "dinosaur with 500 teeth" on September 6, 2019; the account was later deleted[4]. The joke sat quiet for about three months before anti-comedy communities picked it back up in late December, which is where most readers first encountered the warning[5].
- **Platform:** Reddit (origin) / YouTube (viral spread)
- **Creator:** Unknown
- **Date:** 2019
## Overview
The gag works because Nigersaurus, a real sauropod with roughly 500 small teeth, reads close enough to a racial slur when said aloud that the Google result feels like a trap[1]. Posts typically carry a pleading caption asking readers not to run the search, often paired with cartoon dinosaurs or edited screenshots of the Google search bar[2]. A second variant flips the warning and dares the reader to look it up, framing the Don't Google challenge as a prank to run on friends, siblings or unsuspecting parents[3].
The humor sits firmly in the anti-comedy lane: the joke has no punchline on its own, and the payoff only lands if the target actually types the query. Reaction videos filmed that moment of recognition on YouTube, which gave the gag a second life outside Reddit[5].
