The "Infinite Probability Generator" was a probability generator created by Phineas and Ferb to help Baljeet with his problems with taking decisions. To do this, the generator created a clone of Baljeet whenever he took a decision. Later in the episode, Baljeet had made a decent amount of clones, and that's where stuff went bad. The clones and Baljeet argued about Buford, saying that they shouldn't obey him. With this in mind, Baljeet and his clones rebelled against the bully.
