Mel Gibson -- Hits from the Pong

With a giant smile on his face -- and stains on his shirt -- Mel Gibson took over a ping pong table at a bar in NYC this weekend and played a little table tennis with his pal Josh Brolin.

While most of the spectators surrounding the bar room athletes were pounding a drink of some sort, Gibson only had his hands on his paddle.
