Dodgers Star Andre Ethier -- 'This Town Might Burn Down' ... If We Win the World Series

Los Angeles should brace itself ... 'cause if the Dodgers win the World Series, "this town might burn down" ... so says Dodgers superstar Andre Ethier.

The outfielder was out at Madeo last night -- takin' a bunch of people out for a pre-playoff game dinner -- when we asked how he was going to celebrate if when the Dodgers win the Series.

"This town might burn down, eh? But we'll address that when that happens," Ethier joked.

Sure, he was kidding ... but let's get serious -- it's a legit concern ... especially after the Lakers NBA Championship riots of 2000 ... and 2009 ... and 2010.

But it won't happen a 4th time ... will it?
