Leonard complains when he sees that Penny bought his mother's book The Disappointing Child. They talk about the chapter about potty training, bed wetting and masturbation. Leonard says "if something came out of me she wrote about it."
In Penny's apartment, she asks Leonard why a five-year-old boy put on his mother's make-up and put on "balloon boobs". Leonard denies they were boobs, as oppose to muscles and the make-up was green because he was the Hulk. He wrote off the fact that he wore his mother's bra because he didn't want the balloons to get saggy. He says he was the Hulk because he wanted to smash out of the house. One of the reasons he was so angry as a child was his mother designed an Easter egg hunt with no eggs to see how long he would keep looking. He kept looking until June.
Penny seduces Leonard to make him feel better so Leonard uses the book to get out of hanging out with Penny's friends and get takeout and watch The Hobbit Blu-ray with Commentary, have sex at work, watch a six-part documentary on Monty Python and anything he could guilt-trip her into.
Penny tricks Leonard by dressing up sexily and surprises him with a webcam chat with his mother on Skype. She wants to discuss why Leonard keeps involving her in his sex life. When he was six, Leonard walked in on his naked parents while his mother was spanking his father with his new ping-pong paddle and Leonard's mother wanted to know how that made it feel. Leonard had thought that that incident had been a nightmare of his youth. Leonard calls Penny to come back because he's "sad for real".
