Leonard and Penny decide to put their relationship through a 'beta test,' which allows them to report the problems they have with each other as 'bugs,' like a programmer would do with computer software. When they exchange lengthy lists of relationship bugs, Leonard takes it to heart and decides to take Penny to on a real date to a gun range, where he promptly shoots himself in the foot. Meanwhile, Koothrappali buys an iPhone 4s from the mall and falls in love with Siri. Wolowitz and Bernadette become concerned when he starts treating his phone like a real woman. Sheldon and Amy try to achieve internet fame by creating "Sheldon Cooper Presents: Fun with Flags," a video podcast dedicated to the study of flags.
