S02E40 I Was a Middle Aged Robot

Before the father-daughter race with Candace, Lawrence inadvertently loses his memory due to a device in Perry’s hideout. To cover for him, Perry pilots a robotic version of Lawrence. At the same time, Dr. Doofenshmirtz creates a new invention called "Eulg," which serves as the complete opposite of glue, designed to separate items instead of bonding them together.
