In 1949, after decades of making wooden furniture and toys, Ole Kirk Christiansen's small factory in Billund, Denmark, moved to plastic and created the 'Automatic Binding Bricks', which would later be known as LEGO. When the company patented the tube system in 1958, LEGO became the dominant toy line worldwide throughout the 1960s and 1970s. When other competitors capitalized on the expiration of the company's patents in the 1980s, LEGO faced stiff competition until they reported their first loss in 1998. Poor business decisions with film licenses and the failure of the Jack Stone and Galidor lines brought LEGO to near-bankruptcy until Jørgen Vig Knudstorp took over the company and, by bringing it back to its roots, rejuvenated LEGO's profits.
By the time The Lego Movie hit theaters in 2014, LEGO became the largest toy franchise in the world.

Nathan decides to practice his own assertiveness in relationships by challenging Angela over their son's religious upbringing. Angela, a fervent Christian, refuses to allow Adam to be raised in Nathan's Jewish faith, so Nathan secretly brings his son to lessons with a tutor in Judaism under the pretense of swimming lessons. Seeking solace outside the house, Nathan opens his replica Alligator Lounge to the public under the name Nate's Lizard Lounge. The co-parents argue over a comedy skit featuring six-year-old Adam as 'Dr. Fart' and a joke about eating faeces, which Angela claims is a Satanic practice.
Nathan rehearses the confrontations with a fake Angela, and in one scenario, she harshly criticizes Nathan's emotional detachment and questions the ethics of the entire production. However, in their real final confrontation, Angela simply decides to quit the rehearsal. Nathan continues to raise Adam, now as a single parent.

In the second episode, Nathan develops a rehearsal for Angela, a woman considering motherhood. Nathan hires child actors to simulate adopting and caring for a baby and sets her up in a rented farmhouse in rural Oregon. Due to Oregon child protection laws, Nathan's team must covertly switch out the baby every four hours and replace it with a robot baby at night. Seeking a simulated husband, Angela dates Robbin, a numerology-obsessed man who wants to have sex with Angela despite her devout Christian beliefs against premarital sex. When Robbin quits the project due to the robot baby's incessant crying, Nathan inserts himself into the experiment as Angela's non-romantic co-parent.
