When Sheldon meets with the Universityâ€™s Dean, who requests that he leads an arctic expedition to the North Pole, Sheldon asks the guys if they would like to come along. After much consideration, the guys decide to go with him, but they regret it every second during the harsh and cruel training for the extremely cold weather they can be expecting at the North Pole. Meanwhile, Penny hears the news that theyâ€™re going away, and decides to show Leonard that she cares about him by knitting him a scarf. However, he believes there may be secret feelings in the scarf, in which she doesnâ€™t want him to go even though she says she will just miss him.
