Jimmy Fallon and his fellow Saturday Night Live alumni Tina Fey and Amy Poehler played a game of "True Confessions" on Tuesday's Tonight Show.

The game involved every player receiving two envelopes, one containing a fictional confession and the other with a real one. The other players had 60 seconds to interrogate their opponent and figure out which confession was real.

"I was once mistaken for a prostitute in Monaco," Fey confessed and explained that she was traveling in Europe with her cousin in 1992. She laughed throughout the confession, and both Fallon and Poehler believed it was a lie, but in fact it was the truth.
