#DateMe: An OkCupid Experiment is the perfect show for people looking for love, already in love, or who want to laugh… with love.

As a scientific experiment about the online search for love, 38 “undateable” profiles were placed on the world’s most popular online dating site to see if anyone would engage with them. The online conversations and interactions that followed were tracked, measured, and documented. The outcome of this experiment is the hilarious and shocking new show, #DateMe – Get your tickets here!
