Bill Murray crashes bachelor party, shares wisdom

He hasn’t ad libbed a speech this good since “Caddyshack.”

Actor Bill Murray crashed a bachelor party at a steakhouse in Charleston, S.C., over the weekend — offering party-goers a funny impromptu lecture about how to tell when you’ve found “The One.”

Video of Murray’s appearance was posted on Deadspin.com.

“If you have someone that you think is The One, don’t just sort of think in your ordinary mind, ‘OK, let’s pick a date. Let’s plan this and make a party and get married,'” Murray proclaimed.

“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,” Murray said.

The party-goers, many of whom were from Boston College, were thrilled by the surprise guest — who was apparently on a fishing trip.

“At one point during dinner at a steakhouse, one guy goes to the bathroom downstairs and sees Bill Murray sitting with some people with a fishing vest on… One of my buddies then went down and asked if he’d come up and say a few words,” one of the partygoers is quoted as saying. At first the comedy legend demurred. But then, “Two minutes later, Bill f—ing Murray walks into the room.”
