Maybe it’s better when “Lazy EMT” William Medina doesn’t respond to a 911 call.

One day after the now-former FDNY medic was charged with reporting a fake emergency — shouting “I think he’s dead!” into a Queens pay phone so he wouldn’t have to bother with a real emergency in Brooklyn — video has surfaced showing him and a trainee dropping a patient.

Shocked bystanders gasp as Medina and the trainee try to lift a man strapped to a back-board — only for the man to come crashing down again.

The video, taken in July on the Lower East Side, shows the poor patient — who’d been hit by a livery cab — falling about a foot and a half before hitting the pavement.

“Y’all f–kin’ dropped him!” the bystanders shout.

Weeks later, on Aug. 19, Medina had just delivered a patient to Elmhurst Hospital in Queens when a call came in directing him to respond to a sick child in Brooklyn.

He apparently didn’t feel like going all the way to Brooklyn, so he allegedly pulled his ambulance over at a pay phone at the corner of 65th Street and Roosevelt Avenue, picked up the receiver, and dialed 911.

“There’s a man at the intersection of 74th Street and Roosevelt Avenue!” he shouted, according to the criminal complaint.

“He’s not breathing!” Medina allegedly lied. “I think he’s dead!”

The alleged lie sent nearly a dozen emergency personnel — including police officers and a fire truck, plus his own and a second ambulance — scrambling to the non-existent crisis.

Only after making the call did Medina tell his partner, Stephen Choy, what he’d done, a source told The Post. Choy, who had only been an EMT for a few weeks, alerted his bosses to the deception a couple of days later, the source said.

Medina has since quit the job, and former fellow EMTs are saying, “Good riddance.”

“I heard he is a good kid but what he did was f–ked up,” said one. “What he did was bulls–t. He gave every hardworking EMT and medic a bad name.”
