Others knew it was all a prank, Fox News reported.
But it wasn't dangerous according to David and Morris, they just wanted "to make light of the situation" and didn't want to get anyone sick or hurt, WNBC reported.
MTA Chairman Pat Foye didn’t agree with the teens.
"Given the environment, dressing in hazmat suits and walking the streets of New York is an irresponsible thing to do. It ain't funny. You shouldn't do it," Foye told WNBC.
Foye has reported the case to both the NYPD and MTA police, WNBC reported.
