Matthew McConaughey -- Hey, Brad Pitt ... Toss Me a Beer!

No one had a cooler moment this weekend than Matthew McConaughey ... when Brad Pitt tossed him a beer from one New Orleans balcony to another. Alright, alright, alright!

McConaughey was in town for a charity event ... hanging out on a balcony in the French Quarter ... with Pitt hanging out on his own balcony across the way.

At one point in the video, you see Pitt yell to McConaughey, "You need a beer? I'll get you a beer." He then disappears into his home, comes back with a can of beer, and then tosses it several feet ... right to McConaughey.
