20Hurt: The North Pole Excursion
Don’t get us wrong, not everything to do with this storyline was awful. For instance, it was nice to see Penny admit she wished Leonard wasn’t going, and them sharing a kiss when he returned was nice too. However, it didn’t exactly make Leonard and Penny look like they would be a
good couple when it took him leaving for months to make her cherish him.
On top of that, the real issue with this whole storyline was how awful it made the friendship between the guys seem. It was already clear how annoying Sheldon can be, but the idea that his best friends faked scientific results to shut him up makes all four of them look like awful people.
