The Celtics made a bold decision before Game 6 against the Wizards, showing up in all black, most likely in an attempt to mock the Wizards for doing the same back in January. 

Unfortunately for them, they lost the game, which you absolutely cannot do when pulling a stunt like that, and it understandably led to plenty of jokes. Even John Wall commented on it after the game in his postgame interview on the court. 

Isaiah Thomas, however, has no idea what everyone is talking about. 

Asked about the sartorial decision following the loss, and if there were any second thoughts, Thomas played dumb.

"Second thoughts? No, I wear black all the time, so ... I'm the first one in this gym too, so I didn't see nobody else wearing black," Thomas said, barely containing one of his trademark smirks. 

Look, 15 guys all wear the same color outfits to games all the time, everyone knows that. 

Even Avery Bradley agrees, it was just a coincidence. 

CELTICS FANS DO NOT READ THIS NEXT PART

 Of course they coordinated the all black look, I mean, come on, everyone knows it. You tried to be funny by mocking the Wizards for doing it earlier in the year, but it didn't work. Just take the L, and move on. 

CELTICS FANS YOU CAN UNCOVER YOUR EYES NOW.

OK, to be honest, this kind of hilarious to watch them blatantly lie to everyone's face over something as non-serious as this. The NBA is so awesome.
