Regarding the opposite sex, they're on a steep learning curve. In every other sense, they're geniuses. Join physicists Leonard Hofstadter (Johnny Galecki) and Sheldon Cooper (Jim Parsons) as they ponder black holes, chemical deviations, girls, and other mysteries of the universe in all 24 phenomenally funny episode of the Season Five. With Penny (Kaley Cuoco) and Leonard's relationship in uncharted terrain, Sheldon, Howard (Simon Helberg), and Raj (Kunal Nayyar) discover that the feminine mystique is something that cannot be easily graphed or calculated. As they muddle through relationship "bugs" and romance re-launches, they also discover it's nothing a good roll of the D&D dice or a paintball tournament can't solve.
