Lottery: This is one of the only remaining in-person lotteries on Broadway. By showing up two and a half hours before curtain, you can enter to win $32 tickets that will very likely seat you in the front row of the theater. Also, the show's Twitter account often tweets contests to win the opportunity to buy tickets as well.
Rush tickets: There's no rush for this show, but the box office does sell standing-room only tickets for $27 right after the lottery is held.
What you need to know: Showing up for the Book of Mormon lottery is a fun time. It's run by Lottery Dude, who makes the half-hour wait for the draw entertaining. Also, while this show is absolutely hysterical for the open-minded, please don't bring children along. The characters in the show liberally say "f*ck" and poke fun at religion.
