This weekend, Bill Murray will go behind the bar at his son's Brooklyn restaurant and serve up drinks to patrons. The actor's son Homer Murray told local media that his father will be bartending in celebration of the opening of Homer's new dining spot, 21 Greenpoint, adding, "What my dad lacks in experience, he makes up for in tequila." Even though, Murray will be on hand Friday and Saturday night, the event is reportedly invite-only.
