Tommy Lasorda -- TURN DOWN FOR WHAT!?

Here's Tommy Lasorda ... bumpin', grindin' and singin' ... to the Lil Jon classic, "Turn Down for What" ... and it's glorious.

Sure, he's 87-years-old ... but it's clear the L.A. Dodgers legend doesn't plan on slowing down any time soon -- remember, this is the guy who hit a burlesque show just a few weeks ago.

No word on what inspired the 1-man dance party ... but who cares -- get it Tommy.
