Murray said on Twitter that he would will name his new coach on Wednesday, setting the tennis community guessing as to who it could be.
But he confirmed late in the day that it was actually an April Fool's joke - one which pretty much the entire world swallowed hook, line and sinker.
Indeed, for such a prank some may well believe that he deserves to be gunged with thick, green slime - as he was in Miami during a press conference.

Huge names like Pete Sampras, John McEnroe and Martina Navratilova were all suddenly touted as options, while Great Britain Davis Cup coach Leon Smith - who worked with Murray from the ages of 11 to 15 - was also mooted as a contender.
Without taking into consideration the dry and sarcastic nature of Murray’s Twitter account and the fact that it’s April Fool's Day, most British media outlets fell for it and ran it as breaking news, without realising they were being pranked. 
The world should have been more cautious of believing Murray's words on Twitter, of course: he is a known prankster and who broke the news of his impending marriage to Kim Sears just last month - only to backtrack once again.
Murray pulled the same prank three years ago when he posted on Twitter and Facebook - again, on April 1 - that he was hiring longtime friend Ross Hutchins as his new coach.
But the desire to believe that Murray had picked a new man came because the Wimbledon champion has been without a coach since ending his two-year relationship with Ivan Lendl last month.

Until Murray teamed up with Lendl, he had fallen tantalisingly short of winning a Grand slam title.
He lost his first four Grand Slam finals to share a professional era record with Lendl, but finally got over the line at the US Open in 2012 when he prevailed in an epic tussle against Novak Djokovic to become Britain's first male Grand Slam champion since Fred Perry in 1936.
Murray lost to Djokovic in the 2013 Australian Open final but, after skipping the French Open through injury, he thrilled the home fans with his run to the Wimbledon title last summer.
Mats Wilander is another name linked with the position, despite taking to the airwaves to rule himself out last week when telling the BBC Today programme: "I don’t necessarily think Andy needs to be thinking about former Grand Slam champions.
"But I think he needs to be thinking about somebody who has a much better second serve than I do, who knows about second serves, maybe to work with this person for six months, or on and off."
