1 Sheldon's "Discussion" with Alex - "The Egg Salad Equivalency"
This was the scene that made "The Egg Salad Equivalency" my new favourite episode ever, surpassing "The Vengeance Formulation"
The most awkward episode to date
Alex: I have to go...
Sheldon: Well so does this fellow, but he can't leave without it burning like hot soup.
THAT EPISODE WAS FUNNY I STILL LAUGH AT IT
2 Sheldon Grabs Penny's Breast - "The Adhesive Duck Deficiency"
Of course this is a great and new twist.. Like Sheldon has never seen nor touched a breast before and wasn't sure what he had done.
This was funny because Sheldon had no idea what he was doing or touching. Awkward.
Eww I hate breasts, they're disgusting and I'm a male by the way.
