Ep 1. Steve and Snot's Test-Tubular Adventure

Steve and Snot's Test-Tubular Adventure is the premiere episode of the ninth season of the American animated sitcom American Dad. This episode follows Steve and Snot as they undertake a science experiment that quickly goes awry.

The episode begins with Steve and Snot struggling to come up with a project for their science class. They finally decide on creating a clone of themselves using Steve's father's cloning machine. Steve's father warns them not to use the machine and tells them a story about the time he accidentally cloned himself, but they ignore his warning and proceed with the experiment.

After a few attempts, the boys successfully clone themselves, and the resulting clones, who are exact replicas of Steve and Snot in every way, decide to explore the world outside the lab. They quickly become popular with the other students at school and even start dating some of the girls.

However, things take a turn for the worse when the clones begin to develop their own personalities and start causing chaos around the town. They start drinking and smoking, getting into fights, and even stealing cars.

In an effort to fix their mistake, Steve and Snot set out to hunt down their clones and put an end to their destructive behavior.

The episode ends with Steve and Snot reflecting on their mistake and vowing to never use the cloning machine again. They release their last remaining clone into the wild and watch him run off into the sunset.
