Every August, SNL holds an e-mail lottery for tickets to a show, either the dress rehearsal or the live broadcast. You send your contact information but you cannot request a specific date. I applied this past August and was contacted via e-mail that I had won two tickets on September 14 for the September 15 season premiere! My tickets were for the dress rehearsal which is the exact same show plus 30 minutes of extra material. It’s definitely worth entering the lottery, especially if you live in NYC–very fun experience.
