Of course, by that time, yet another unsuspecting victim in the Vegas dressing room likely will have fallen prey to one of Fleury's much-ballyhooed pranks.
Golden Knights defenseman Shea Theodore, for one, has been on the wrong end of one of those. Earlier this season, Fleury tied empty bottles to the bottom of Theodore's car. When Theodore heard rattling coming from the undercarriage of his vehicle while driving to the airport, he thought there was a serious mechanical failure.
In reality, it was just Fleury being Fleury.
"I think that's why he's been able to have as much success as he has. He's always having fun like that," said Penguins center Sidney Crosby, Fleury's close friend and his teammate with Pittsburgh for 12 seasons. "For him, it's still as much a game as a business."
For the record, Crosby is familiar with the stunt pulled on Theodore. Fleury did the same thing to Pittsburgh center Evgeni Malkin during his Penguins days.
"The thing is, for him to get to 400 will be huge," Crosby said. "It shows endurance, it shows perseverance, it shows skill.
"Besides, you don't see many goalies enter the NHL at age 18 anymore as he did."
Fleury was selected No. 1 in the 2003 NHL Draft, the third goalie to be the top pick. Michel Plasse (Montreal Canadiens, 1968 NHL Draft) and Rick DiPietro (New York Islanders, 2000 NHL Draft) were the others.
In the subsequent 12 seasons, Fleury rewarded the Penguins for their confidence in him. He was a member of three Stanley Cup championship teams in Pittsburgh (2009, 2016, 2017) before being selected by the Golden Knights in the NHL Expansion Draft on June 21.
