Unable to get Stone to figure out that he’s singing the Springsteen classic, Fallon started to simulate giving birth and holding babies.

“‘Born in the U.S.A.!” Stone shrieked.

“What you’re saying is inappropriate,” Fallon commented.

Thanks to Stone’s impressive impersonation, Fallon figured out her song in no time.

Fallon then had to sing Elvis Presley’s “I’ll Have a Blue Christmas Without You.” Once again giving his best impression of the King, Fallon sang with Elvis’ signature deep vocals.

Stone couldn’t figure it out until Fallon gave it a goofy spin.

The duo had time for one more, so Stone was assigned “Baby Got Back,” but had to sing the lyrics, “I like big butts and I cannot lie.”

Once again Stone gave it her all and shimmied her booty on top of a chair.
