Vice President Biden on Monday joked that he now assumes every microphone is on, in a reference to his expletive captured at the White House during the 2010 signing of the healthcare law. 

"Piece of advice about that BFD stuff: Assume every microphone is on," he said, according to CNN.

Biden was speaking at the Ride 2 Recovery Memorial Challenge, a 350-mile bike ride from Washington to Virginia Beach that included injured veterans. 

The person who introduced Biden referenced the vice president’s off-the-cuff remark to President Obama after introducing the president at the ObamaCare bill signing four year ago. 

"This is a big f---ing deal," Biden said at the time. 

"I just want you to know, I didn't intentionally say that," Biden told the crowd of cyclists Monday. "I actually turned and I said, 'Mr. President,' and I whispered in his ear. Unfortunately, I was looking in the direction of one guy who could actually read lips - not a joke. Because no one picked it up at the time and one of the reporters read lips. Thank god my mother was gone or I'd have been one dead vice president."
