Is there anything Emma Stone can't do? The La La Land actress was a special guest on Tuesday's season finale of NBC's variety series Maya & Marty . In addition to playing a ghost intern alongside Mikey Day in the "Office Ghosts" sketch, Stone and host Maya Rudolph also performed Robyn 's "Call Your Girlfriend" using butter tubs. The cover was inspired by a black and white video of the Swedish band Erato performing the song with empty containers. "I saw this thing on YouTube a couple years ago of these three girls in their kitchen in Sweden singing a song, playing butter tubs, and I've been practicing ever since," Rudolph said.
