NBA Star Chandler Parsons -- My 25th Birthday Was LINSANE!!

Houston Rockets star Chandler Parsons turned 25 years old the other day ... and he celebrated with his teammates ... but the party looked more like a scene from "Office Space" with really tall people.

Parsons and his co-workers -- Dwight Howard, Jeremy Lin, James Harden and more -- hit up Mr. People's in Houston over the weekend for a shindig sponsored by Buffalo David Bitton.

The party looked fancy ... with ice sculptures, champagne, gift bags and gourmet cake -- the works.

But when we clicked through the pics, we kinda got the impression that it was more of a work function than a rager bday party.

You know what we're talkin' about -- like when someone in your office has a birthday and you feel obligated to go to the party because you don't wanna be that guy who blows off the team. But when you go, you're really just plotting to sneak out so you can say you made an appearance. C'mon, you know you've all done it. That's kinda how everyone at this party looked.

Anyway, HAPPY BIRTHDAY CHANDLER!
