(CNN) Time to hit rewind.

The first ever YouTube video was uploaded on April 23, 2005 -- exactly 15 years ago, today.

YouTube co-founder Jawed Karim posted the 18-second video, titled "Me at the zoo." It has since garnered over 90 million views. To this day, it is the only video on Karim's channel.

Upon clicking play, the screen fills with a young Karim's face, his disheveled hair taking up the screen front and center.

"Alright," Karim begins. "So here we are, in front of the elephants."
