Ep 4. Lincoln Lover

The second season of American Dad brings us the fourth episode named 'Lincoln Lover'. The story revolves around the family of CIA agent Stan Smith and their rather unusual fascination with Abraham Lincoln, which is triggered by Stan's wife Francine. Her patriotism and love for the 16th president of the United States rubs off on their son Steve, who begins to show an equally intense interest in all things Lincoln.

Steve begins collecting Lincoln memorabilia and develops a fixation with completing his Lincoln face collection, which leads to an addiction to Lincoln coins. When Steve's dad Stan finds out about Steve's obsession with Lincoln coins, he is less than pleased and demands that Steve return the coins to the CIA before the organization discovers his secret stash.

Meanwhile, Roger, the resident alien in the family, becomes addicted to the world of online gaming and begins neglecting his duties around the house. His addiction reaches its peak when he becomes so obsessed with the game that he decides to create a virtual Lincoln statue in the game, which he plans to sell online for profit.

As the story progresses, Steve must decide whether his love for Lincoln extends beyond just his coin collection, and his devotion to Lincoln is tested when he discovers that someone has stolen the virtual Lincoln statue that Roger created. Determined to get back the statue, Steve and his friends form a plan that would put them in harm's way.

As Francine begins to realize the impact that her love for Lincoln has had on her family, she begins to feel guilty, causing her to lose interest in Lincoln and her patriotic ways. Meanwhile, Stan's attempts at rehabilitating Roger prove futile, and he is forced to take action when Roger becomes a danger to himself and the family.

Overall, 'Lincoln Lover' is a hilarious episode that tackles addiction, obsession, and patriotism. It also highlights the impact that our interests can have on our families and whether we would be willing to put ourselves in harm's way for them. The episode delivers an excellent blend of humor and social commentary that will keep you entertained from start to finish.
