On Friday, Miley Cyrus joined Jimmy Fallon on The Tonight Show for a game of “Phone Booth,” in which both participants had to answer basic trivia questions to avoid their respective phone booths being filled up with mystery guests.

Miley’s first question: Can you name three U.S. states where it’s legal to smoke marijuana?

She got Colorado, but her other two guesses weren’t exactly close. Her punishment? The addition of a very hairy tarantula to her booth. Watch the clip below to find out where Miley thought it was legal to light up.
