Bill Murray was helping out at his son's Brooklyn bar over the weekend and seemed to be enjoying himself as he served drinks, drank tequila and sang along to the Rolling Stones' track 'Miss You'.

It's not the first time Murray has hopped behind the bar. During SXSW 2010, in Austin, Texas, the Groundhog Day star volunteered to bartend at the Shangri-La pub. Whatever the drink request from patrons, Bill ignored them and served them only tequila shots.

Check out the footage of Bill Murray below.
