His grant to go the the to look for evidence of slow moving monopoles has been approved. Leonard perked up that the president offered to send him north. Sheldon replied, "In fact, he was quite enthusiastic. He said 'quite frankly, if I could send you tonight, I would." Sheldon’s interest in going is incredible since he has to leave the if he gets a brain freeze from his.

Leonard, Raj, and Wolowitz are excited about being Sheldon-free for three months and all the small victories they will have like sitting in his spot. On the contrary, Sheldon proposes that they accompany him as his support staff for the project. At first they decline to spend three months in a hut with an "anal nut bag," as Howard puts it. Finally they decide to go along to be part of the team that make such shifting discoveries. Raj figures that due to his suffering it will result in a payback of a "well-hung  with wings" in the next life. Howard feels that he will become famous as the engineer that designed the that killed Sheldon.

Sometime later, Sheldon goes over to ask Penny a favor by knocking on her door. Before he can perform his second set of knocks, Penny echoes him with “Knock..knock..knock...Sheldon”.

Penny reminds him that she had already told him that the freezer is cold enough and safe enough to keep his hamburger fresh. He really wants to borrow it so they may practice acclimating themselves to the cold for their expedition to the North Pole for three months.

Penny declares that it is no big deal and that she’ll check on the icebox thingie. Leonard wonders if she is upset and Sheldon correctly guesses that she is.

Raj paints sideburns and a on a six inch high action figure. Howard must operate using a vintage game. None of the guys is accomplishing his task in the cold, when they realize that they could assemble the equipment in the warm cabin then taking it outside.

While enjoying a with a stick of  or a stick of "" for the  Leonard, Raj is in an argument with his parents about going on the North Pole. Howard had convinced his mother to let him go so he puts them on the phone together. Then she cries, “? I thought you were going to !” Penny asks to see Leonard to is happy to removed himself from the arguments. Penny then presents him with a blue with, a , somehting she saw on an , to keep him warm while he does his science stuff. Penny hugs him, which Leonard returns.

After considering that they are at the top of the world they decide on a movie marathon of “” and “”. Howard whispers to Raj to forget the crossbow, and find him an icicle.



Critics
"The Leonard and Penny relationship has been on the back burner all season and so this low key acknowledgment of her feelings felt appropriate. The show is probably going to be around for years to come so the producers are in no hurry to change the dynamics of the group yet...Instead of that scene we could have been exploring how Leonard and Penny feel about each other and why. Again there are so many simple things which the show could do to help build their relationship up as a more realistic entity...This episode sums up the whole of season two of the show. It’s too reliant on Sheldon, not focused on character development and too static for my tastes. On the flip side it is also funny, consistent and showcases a genuinely strong comic character." - The TV Critic's Review
