According to internet legend, the actor has a habit of turning up at random private parties in New York, whispering, "No one will ever believe you" to a random guest, and then hitting the road.
Occasionally, his shocked hosts manage to grab a photo with him before he disappears into the night…
Now the internet tells us that Bill is embarking on a party crashing tour of the USA.
A website called SuperOfficialNews.com (sounds legit, huh?) quotes Bill's agent Paul Horner:
"Mr. Murray is looking to take a vacation around the United States. He's hoping that if he shows up to your party with a bottle of wine or vegetable tray, you will be able to make the proper accommodations for him. This includes allowing him to sleep on your couch or in a spare bedroom, both of those options being completely acceptable.
"All we ask is that if Mr. Murray does decide to crash your party, please give him his space. He's a human being, just like you and me. He's just looking for a good time and a fun way to connect with fans.
"At these parties, Mr. Murray does not want to be called 'Bill Murray' but instead wants to be referred to as 'Kaiser Soze'. Activities that Mr. Murray enjoys are drinking and karaoke. Having those two things at your party will definitely increase your chances of him making an appearance. Also it is extremely important that any house or location interested in participating have a sheet or banner of some kind attached to their establishment the night of the party. It must say in big bold letters, 'BILL MURRAY CAN CRASH HERE'. This will let Mr. Murray know at what locations he is welcome."
So that would explain all these photos floating around the internet in the last few days…
Do you reckon this is for real?
