I was a musician playing at the Beauty Bar in Austin during SXSW a few years ago. Bill Murray turned up to the party and jumped behind the bar. He asked me what I wanted and I asked for a whiskey coke. He came back over and said &quot;Shot &#x27;a tequila and a beer!&quot; He handed me my drinks, winked at me and moved on. Just about every single person who saw him that night had a better night because he was there. That&#x27;s a pretty interesting effect to have on people.
