20 years ago today, the "Did you know" section appeared on English Wikipedia for the very first time! Here's how it looked.

Since then, we've featured more than 100,000 facts on the main page. We like to think that we've gotten a little better at choosing surprising hooks.

In case you were wondering, the most-clicked "Did you know" entry was the article "Infant swimming" in 2014. More stats here:

@wikipedia My little brother felt under-represented so I created the bot that did 99% of those clicks.

JK.

@funcrunch @wikipedia it is very fitting that that post reminded you of me... because I am the one who posted that! A few people run the wikipedia account and I'm one of them :-)

@annierau @wikipedia

Oh sorry I didn't know you were on that elite crew ;-)

@wikipedia they don’t actually work though – an utterly pointless failure of a design in which the blade simply strokes the blunt pencil

@wikipedia

That's actually a pretty good hook (or maybe anti-hook) - it leaves me wondering what are the surprising pencil-sharpener facts you're not telling me.

And when they first starting making twin-size pencil sharpeners. And what's the largest number of hole sizes included in any commercially available pencil sharpener. And whether the holes represent standardised conical shapes. And whether there have been innovations to minimise tip breakage just when it's almost perfectly sharp ...

@wikipedia I want there to be a did you know that somehow connects a rocket to a pencil
