If Charles Woodson needs work after pro football, he's got a future as a water boy.

Woodson spent his final minutes as an NFL star as a butler, grabbing drinks for parched Raiders teammate Khalil Mack. And he added in a few jokes, too.

Via Oakland Raiders on Twitter:

That's perfect form by the 18-year pro. He even grabbed two separate drinks for Mack's two separate positions.

Bottoms up, Khalil. No. 24 won't be on the sideline to help you rehydrate in 2016.
