Serial event-bomber Bill Murray has blessed a couple's impending nuptials with his visage, getting in on their engagement photo while wandering about Charleston, South Carolina.

What would otherwise have been a pretty cheesy photo was infinitely improved by the Lost In Translation actor's presence, who looked as nonchalant as ever as he posed next to couple Ashley Donald and Erik Rogers.

Photographer Raheel Gauba posted the snap to Facebook, and explained to the Huffington Post exactly how it went down:

"We were walking around downtown Charleston, taking in the romance of the city and enjoying the scenery. I found this staircase and asked the couple to go get comfortable. Now when I do these shoots, sometimes I get tourists whistling or making funny faces or simply congratulating the couple. When I set up Ashley and Erik, I saw this look of surprise on their faces as they looked over my shoulder. I asked them to look at the camera, but they just looked stunned and with his eyes, Erik motioned that I better look behind me. As I turned around to potentially ask the person distracting them to give us a moment, I see Bill Murray with his shirt up, belly out and patting it -- his attempt to make the couple laugh. I joined the couple in the shock and surprise of the moment. At that point, I invited him to join the couple for a quick shot and he did. So genuine and nice of him to make the couple's day!"

Remarkably, this is not the first instance of Murray crashes wedding-related events in South Carolina this year.

Last month he turned up at a bachelor party in Charleston and imparted some words of wisdom on the guests, saying in an impromptu speech:

"If you have someone that you think is The One, don't just sort of think in your ordinary mind, 'Okay, let's pick a date. Let's plan this and make a party and get married,'" he said. "Take that person and travel around the world. 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."
