|Walden to Berta|
Before the show
Walden grew up as the child of a single parent when his magician father disappeared early during his childhood. He also spent the first four years of his life living with a gorilla, which his mother Robin explained to him was his "brother", Magilla but in reality was an experiment she carried out to see if humans learn faster than gorillas (One False Move, Zimbabwe!). During high school, he started to date Bridget, who would later become his wife. After flunking 8th grade, his mother had him evaluated, and the results were that he go through high school. He therefore skipped it but ended up quitting MIT (it is unknown if it was for the same reason). By the age of 19, he had made his first $1 million. After this, he made a website with Billy that Microsoft bought for? $1.3 billion and bundled with their Zune, further enhancing his riches.Most likely to be the final event before his debut on the series, his wife Bridget threw him out of the house, announcing she wants to divorce him.
Unlike Charlie, who was obsessed with sex and booze, Schmidt is much more concerned with his recent divorce and doesn't take sex for granted. According to his ex-wife, Bridget, he is emotionally immature. This was proven to be fact. For example, he stated that unless Bridget would take him back he would drown himself, but later changed his mind after finding out how cold the water was; also his mansion has arcade games and Sci-Fi mannequins.
He's not self-conscious about his body as he doesn't seem to be at all embarrassed about undressing in front of Alan or walking around the house naked even though Alan, Berta, Jake and Judith all see him. He is indifferent towards Jake. Walden is easy to trick despite warnings from others, such as when he was warned by Berta of Alan's intentions to stay permanently but despite Berta's warnings, Walden invited Alan and Jake to stay at Charlie's beach house after his death or when Alan warned him that Evelyn would try sleeping with him. He is oblivious to Berta's attraction to him and because of his childish nature, he once hired her as a live-in housekeeper, but she quit the "live in" part of the job, staying on as housekeeper due to Alan being allowed to stay due to Walden's friendship with him.
Walden is willing to go for an idea if it involves something he likes such as when he took a restaurant idea from Jake because of the great food deals. He is very trusting of Alan, seeing him as his best friend and has great concern for him such as when he had a mental break down and thought he was Charlie. He and Jake took Alan to a mental hospital after Alan got in Walden's shower. They told Alan that they were going to Las Vegas
Thanks to his experiences with the Harper family (Mostly Alan and Jake), Walden has begun to mature emotionally, but not into an exactly bright person. Despite his emotional immaturity, he is quite smart, as he has designed a website Microsoft bought, as well as he knew what the difference between organic and force fed meat. Walden has also formed relationships with Alan, Jake, Berta, who initially had a crush on him, Judith, Herb and everyone else in Malibu. He was once dating Rose, Charlie's former stalker, and Zoey, a foreign woman with a daughter named Ava. Because of Walden's immaturity, he is great with kids, such as Ava.After a night of having drinks at the local bar with Alan, Walden decides he doesn't want a woman that only wants him for the stuff he has (a billion dollars, etc.) rather for himself. Walden creates a fake identity and manages to find a woman named Kate, a talented seasmstress who is poor and is just passing by. Kate and Walden are currently really in love with each other despite Walden's fake identity. Walden uses his money to secretly help her to become a fashion designer to the stars. However between some trust issues to work out upon his reveal of his big ruse, and her newfound success, the couple barely see one another.
Walden had a beard and long hair in the first half of Season 9. In the episode, "A Possum on Chemo" Walden shaves his beard and gets a haircut. He is a tall and very good-looking man. His looks, along with his vast wealth, have gotten many women attracted to him.
A recurring joke on the show is that Walden's penis is surprisingly big. This was first mentioned after he got undressed right in front of Alan, and Alan walked away muttering to himself that Walden was "hung like an elephant." Later in that same episode, Walden, whilst completely naked, met Berta, whom among seeing his penis and meeting him, responded with "I'm impressed." His old friend, Billy Stanhope, has referred to Walden's penis as the "Python." When Walden and Jenny woke up naked in bed together, she looked under the covers at Walden's penis, and she was shocked by its size.
They were married and Bridget didn't want him anymore, so Walden tried to win her back, but it didn't work. After that Walden started dating Zoey, Bridget told him to sign the divorce papers, so he did. As he did, Bridget wanted him back. Walden didn't know what to do, when she wanted to sleep with him, he told her everything, he hoped to be friends but they didn't.
She kissed him on the lip from episode Big Girls Don't Throw Food.
He proposed to Zoey amid fireworks and a Michael Bolton serenade. But she shot him down. He made several attempts to woo her back, but they never materialized.
Walden wanted to date a girl who wasn't after him for his money. He goes by the name Sam Wilson and befriends an upcoming fashion designer, Kate. He even moves in with her and finances her clothing line in Alan's name. He reveals the truth about himself and she breaks it up with him. They do try to give their relationship another shot, but due to their conflicting schedules, decide to part ways.
Stacey is a dim witted girl. She majored in Communications, but failed to talk (communicate) with Walden on their date.
Linda is Stacey's grandmother. She is a talented photographer.
