Over lunch, the boys and Leslie are discussing Penny's growing obsession with Age of Conan, and Leslie says that "Tinkerbell just needs to get her some". Sheldon decides to solve that problem when he spots Blaine sitting behind them in the cafeteria. He innocently asks Blaine if he's currently in a sexual relationship, and then if he's interested in being in one. Blaine assumes that Sheldon is asking for himself and happily writes his phone number on Sheldon's hand. Leslie watches this exchange with a wry grin on her face, then says "Dumb ass ..." (0203).
He is played by Tyler J. Olson.
