We don’t need to tell you that Bill Murray is a living legend, but here’s some more evidence anyway.
While out on a routine stag night (or bachelor party, as it’s known in the states) in South Carolina, a party goer identified only as Stephen spotted the Ghostbusters actor sat enjoying a steak in the same restaurant.
"We talked to the waiter to see if we could send him some drinks, to which Bill declined,” explained Stephen.
"One of my buddies then went down and asked if he'd come up and say a few words for (the groom) EJ and got a 'No thanks.' My buddy comes back up dejected and tells us it's not going to happen.”
What happened next is probably the best thing that could happen to any man on his last night of freedom.
“Two minutes later, Bill f***ing Murray walks into the room and gives this speech," Stephen concludes.
The speech, captured on film, covers Bill’s advice on deciding whether the woman you love is really the one.
"Take that person and travel around the world," he starts.
"Buy a plane ticket for the two of you to travel all around the world, and go to places that are hard to go to and hard to get out of. And if when you come back to JFK, when you land in JFK, and you're still in love with that person, get married at the airport."
In the extended video, Murray then picks EJ up, gives him a few bumps then walks out of the room.
if that doesn't make it into the Best Man's speech, we don't know what will.
