After Penny brings it up, Leonard discusses a part in the book called the “breast-feeding crisis.” He explains that he favored the left breast so his mom became a little lopsided. Penny laughs and says: “oh my god, you still go left!”

At Penny’s apartment, Penny brings up the book again. She asks Leonard why he wore his mom’s makeup and “balloon boobies” when he was 5. Leonard defends himself saying it was green makeup because he was being the Hulk. The balloons were his muscles. Penny points out that it says he was wearing a bra as well. Leonard tells her it was to keep his muscles from sagging. He then tells her that he was the Hulk because he wanted to smash out of his house. He never liked how he was always part of his mom’s experiments like when she made a fake Easter egg hunt with no eggs and waited to see how long he would look for him to stop looking.
