Bill Murray crashed a bachelor party over the weekend.
The 'Kingpin' actor offered words of advice at the celebration after he was spotted dining in the same restaurant in Charleston, South Carolina.
One of the groom's party had offered to send the actor and his friends drinks, as well as asking him to come and say a few words to the groom, known as E.J.
Although Bill initially politely declined, he approached the party a few minutes later and gave a few choice words.
In a video posted on Deadspin.com, he says: "Listen here, I'm going to give you all advice because it's too late for this guy [the groom].
"If you have someone who you think is the one, don't just sort of think, 'OK, let's make a date, let's plan this and make a party and get married.'
"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 at JFK, and you're still in love with that person, get married at the airport."
The 'Ghostbusters' star - who is famous for his random interactions with ordinary members of the public - also encouraged the bachelor party to have fun.
He added: "You know how funerals are not for the dead, they're for the living? Bachelor parties are not for the groom, they're for the unmarried."
