It was the final straw for passengers onboard a flight waiting to take off from Miami on Saturday.
American Airlines Flight 1469 from Miami to Houston had already been delayed for eight hours when time came to finally depart.
The aircraft was taxiing to the runway when it had to turn around and return to the gate because two passengers were refusing to wear facemasks.
The duo wasn't keen to wear masks for the two-and-a-half-hour flight and didn't seem to care that their attitude held up everyone else on the plane.
While these situations are often met with anger from fellow passengers, that wasn't the case on Flight 1469. Instead, the plane burst into song.
"Na na na na, na na na na, hey hey hey, goodbye," people can be heard singing in video as the pair are removed.
American Airlines confirmed the incident, minus the singing, in a statement.
"American Airlines Flight 1469, with service from Miami (MIA) to Houston (IAH), returned to the gate to deplane two customers who refused to comply with crew member instructions or adhere to federal face covering requirements," the airline said.
"We thank our team members for their professionalism and apologise to our customers for the inconvenience."
