The Internet's beloved video game developer and co-founder of Valve Gabe Newell turned 50 today.

Tumblr user Nest of Vellum was all ready to add this caterpillar to a friend's insect collection -- and to celebrate, they decided to throw it a final birthday party.

But the pics were so charming, they had no choice but to let it live.

Awww.

Mondays are for mammoth bones!

Happy 65th to Larry David. May he never stop teaching us all the things.

Ferociously independent DIY champion Ian MacKaye turned 50 today. FIFTY. That's pretty hardcore.

As the figurehead for hardcore heroes Minor Threat and post-hardcore prototype Fugazi, it's difficult to make an Argument against MacKaye's musical legacy. Strange to think he's half a century old now, isn't it?

Remember those 1,000-something $5 concerts Fugazi did? Well, you can watch 800 of them here. Consider it your Red Medicine for the day.

IMPORTANT QUESTION THOUGH: Does MacKaye still have the straight edge?
