Adam Sandler just polished up another uncut gem.

The man who brought us “The Hanukkah Song” premiered his new coronavirus anthem, “Quarantine Song,” on Thursday’s at-home episode of “The Tonight Show Starring Jimmy Fallon.”

The “Saturday Night Live” alum’s uplifting, not-totally-parody track pays heartfelt homage to health care workers fighting on the front lines of the COVID-19 pandemic.

“Doctors and nurses will save us from this mess if we get them the supplies that they need — and I hope they save us soon because I’m really, really sick of my family,” Sandler, 53, belted out while wearing some cool mirrored shades “so you can’t see me peeking at my notes so much.”

Accompanying himself on electric guitar, Sandler crooned to Fallon, “Doctors brought us into this world as babies, and doctors take good care of your grandma … Nurses slap you around ’til they find a good vein, they wear Crocs — and they tell you the TRUTH!”

He also touched upon some tough realities: “We’ve got to build some more ventilators and make some more masks. We’ve got to do it now, so let’s all come together. I’m teaching math to my kids, and that can’t be good for America.”

“Stay home as much as you can, be sure to wash your hands, let’s make this damn thing go away. We love you, doctors and nurses; you’re saving lives every day. Find a cure for this s - - t ’cause I really, really miss hugging my mailman.”

All jokes aside, a soft-spoken Sandler opened the song by telling 45-year-old Fallon, “Hey, Jimmy, I love you. Keep doing the good stuff you’re doing for us.”
