Quivers last month revealed she had been working from home while she battled uterine cancer. Now cancer-free, she went back to the office Wednesday morning, The Hollywood Reporter said.
Stern, who has vowed to quit his show if Quivers ever left, welcomed his sidekick back by playing music and tossing rose petals in her honor.
"It's pretty amazing," Quivers told listeners. "I was brushing my teeth this morning and thinking about going back on the air for the first time after surgery and how incredibly difficult that was. And today not feeling anything at all. It was just a normal day. You can get up and brush your teeth, throw on your clothes and run out the door. Seriously, I've been praying for this day, and I'm really happy that you are here, and it makes me very, very happy."
