Overview

Bill Murray as an internet meme refers to the folk-hero mythology built around the Ghostbusters and Groundhog Day actor's habit of showing up unannounced at strangers' weddings, karaoke rooms, and house parties1. Fans share photos and first-person accounts, and the punchline is often a line Murray reportedly whispers before disappearing, 'No one will believe you'2.

Alongside the surprise-appearance folklore, 'Bill Murray' also works as internet slang for a duplicate forum post, a joke borrowed from Groundhog Day where the same day repeats without end4. The two threads together made Murray one of the earliest actors whose off-screen antics fed an ongoing stream of user-generated meme output3.

Date

2006

The earliest documented internet usage came on November 6th, 2006, when Urban Dictionary user Earl @F365 posted an entry defining 'Bill Murray' as the constant repetition of a topic on a message board, a joke tied to Football365 forum culture and the endless-loop premise of Groundhog Day4. Three years later on November 9th, 2009, Urban Dictionary user Lorrie the Freak added a verb form, 'Bill Murrayed,' extending the same joke to describe a reposted thread4.

Parallel to the Urban Dictionary lore, a Facebook fan page launched on December 27th, 2008, which drew more than 790,000 likes over the following six years3.

How It Spread

Tumblr picked up the actor as fan-blog material, with fuckyeahbillmurray, billmurraydoeswhathewants, and a blog simply titled billmurray all cataloging photos of Murray with fans and stills from his movies3. On January 5th, 2011, TheChive published an exclusive photo set from a user named Mike who claimed Murray had knocked on his karaoke room door in NYC, joined the party for roughly four hours, bought a round of Chartreuse, and sang an Elvis duet 'Marie's the Name'1.

An August 2010 GQ interview asked Murray about the growing collection of surprise-appearance stories, and he neither confirmed nor denied them3. On January 17th, 2014, Murray hosted a Reddit Ask Me Anything to promote The Monuments Men, answering questions about golf in Ireland, his family, and the legend that he steals fries from strangers' plates while whispering 'no one will believe you'2.

How to Use This Meme

There is no single template. Sharing a Bill Murray meme typically means posting a photo of the actor turning up at a fan's event, retelling a first-person 'I met Bill Murray' story capped with the 'no one will believe you' tag2, or using his name as forum shorthand to flag a reposted topic4.
