During his monologue, Fallon joked about the freezing temperatures New Yorkers have experienced during a powerful winter storm that dropped massive amounts of snow across the country over the weekend.

"It is brutal out there," Fallon said. "It is so cold my belly button went from an outie to an innie."

"We got a foot of snow here in New York City, and everything went from beautiful to brown mush in two seconds. Basically the entire city pulled an avocado."
