In celebration of its own 10th birthday, YouTube gave the Internet the best present it possibly could have: the above mash-up of every monster YouTube hit ever.
Set to Blackalicious' "Alphabet Aerobics" (a video worth watching in and of itself if you haven't already), the video covers everything from "Gangnam Style" to "David After the Dentist" to Grumpy Cat to that idiot who got kicked in the head by a train that one time.
It's well worth your time to spend two minutes and 45 seconds paying tribute to the greatest procrastination tool that will ever exist.

Shake one out for YouTube, y'all.
