The funny pair both got cards with random words written on them, such as belly button and E-cig, and had to work them into a casual conversation as casually and seamlessly as possible.
Silverman first claimed that her New Year's resolution was to "hunt more" in order to sneak "moose" into their opening chat, while Fallon said he beat animals to death "like a piñata" to fit his in word in the most gruesome way.
Apparently, the late-night host even uses a hoverboard to chase down his prey.
Silverman quickly turned the conversation back to animals, however, by saying she was thinking about her "beaver," prompting Fallon to fall on the floor in laughter.
"It's not what you think!" the stand-up exclaimed. "It's what I call my p-ssy."
Needless to say, that didn't help Fallon's composure.
"The Tonight Show" airs at 11:35 p.m. on NBC.
