Actor Bill Murray made one lucky couple's day when he stopped on the street and became part of their engagement photo shoot.

The Post and Courier reports that Ashley Donald and Erik Rogers were posing for engagement photos around downtown Charleston, S.C. when they were suddenly distracted by someone standing behind the photographer, Raheel Gauba of Fia Forever Photography.

The rest is best explained by the folks at Fia Forever themselves, via a blog post on their site:

What an interesting day we have had today! Today is the day that will go down in history for us ? Today, we went viral.

It all started with an innocent little engagement shoot in downtown Charleston with our lovely couple Ashley Donald & Erik Rogers. We were roaming the streets of downtown Charleston (the most romantic city in the country, btw) doing their engagement pictures? and most of the time when I have an attractive couple, you get to hear all sorts of noises around you ? from whistles, to "you look hottttt" to "congratulations!" ? I set the couple down on that little staircase to get ready for a shot and I hear people talking in the back and as I'm looking through the lens, the couple seems stunned and distracted? I think to myself ? oh great, someone is bothering them ? I turn around and I see Mr. Murray standing there with his shirt pulled up and belly proudly on display which he is patting pretty loudly in an attempt to make the couple laugh ? Needless to say I was stunned and I invited Mr. Murray to join the couple for a quick shot ? He obliged and congratulated them and went on his way? leaving behind an extremely happy couple and this photo that will be forever remembered by this couple (and us!!!).

Just last month, Murray crashed a bachelor party and gave the groom some marriage advice.
