Season 7: Episode 14 - The Convention Conundrum

The Convention Conundrum: When the guys are unable to get tickets to this year's Comic-Con, Leonard, Wolowitz, and Koothrappali decide to buy scalped tickets from a stranger, but they worry about getting caught with fake tickets and arrested. Sheldon refuses to buy scalped tickets and instead opts to start his own convention, leading him to search for a suitable star to appear on one of the panel discussions. After a lot of rejections, Sheldon tracks down James Earl Jones at his favorite sushi restaurant in LA and miraculously winds up bonding with the iconic actor. The two share a night full of adventures and James invites Sheldon and the guys to attend Comic-Con as his personal guests. Meanwhile, the ladies try to have fun like mature adults by going to a new tea place at a popular local hotel, but they all wind up feeling that growing up is overrated.
