23 Things That Happened Since 'Oops!... I Did It Again' Debuted That Will Make You Feel Ancient

Oops, you just realized how freaking old you are.

Queen Britney Spears' sophomore album Oops!... I Did It Again came out 15 years ago today, I'll repeat: 15. And although it feels like just yesterday that Brit rocked our worlds with killer dance moves in her red leather jumpsuit, we're here to assure you that it definitely was not. ("Lucky" and "Stronger" are also both from this album and don't you dare forget it.) Here's everything that happened between May 3, 2000 and today, and remembering it all will make you feel old as hell.

August 2000: Kylie Jenner turned 4-years-old

And now she posts pics like this.

Your obsession with Penny Lane started centuries ago.

WTF is that thing?

2002-ish: You weren't cool unless you owned a trucker hat

Why, god, why.

April 2002: Nelly's "Hot in Herre" was your jam

And his face bandaid was the coolest accessory known to man (besides the trucker hat, obv.)

March 2003: Sean Paul's "Get Busy" replaced "Hot in Herre" as your favorite song

The idea that youngsters out there have no idea who he is is just sad.

We finally got that SOB.

How come we can still recite every word?

BRB, still crying.

We still don't really know WTF happened and we like it that way.

There was a world before them, believe it or not.

Basically, when we were all f---ed.

And their marriage still doesn't seem legit.

Now she kicks it with Tony Bennett.

November 2008: Twilight premiered

Which you could argue started everyone's concerning obsession with vampires.

The presidency that (feels like it) never ended.

Still too soon.

April 2011: The world stopped to watch Prince William and Kate Middleton get married

Giving false expectations to every girl on the planet.

Wait, there was a Tonight Show pre Jimmy Fallon?
