A Dad Cartoon is the second part of the 1st episode of season 3 in Dexter's Laboratory, which first aired on November 16, 2001. The episode stars Dad as he tries to clean the family car, only for him to break more things as he does so.
Dad heads out of the house and decides to clean the family car. He sprays the car using the garden hose, but instead washes the inside rather than the outside. Dad gets inside the car, rolls the window up, and cleans the water. He rolls the window back down too fast, but ends up breaking the roller off of its hinge. He tries to force the roller back into place, but he ends up breaking the entire door down as a result. Dad takes the car door and washes it with the hose.
Inside the car, Dad is using a shop-vac to clean the seats. While cleaning, he sees loose change and reaches for them, in addition to kicking the car into drive. The car rolls down a hill and crashes into a tree. The tree then falls on top of the car. Back in the front yard, Dad hoses down everything. In the car, he uses cleaning spray on the car radio, but a cassette tape pops out. A montage of him getting hurt is then shown. In frustration, Dad throws everything at the car, and forcefully pushes it down a hill. The car then lands on top of other cars similar to the one Dad just "fixed." Dad then enjoys his moment of pride.
This episode marks the debut of Dexter's newly designed house in the new animation style.
In this episode the car is blue, but originally Dad's car was green.
Dexter, Dee Dee and Mom do not make an appearance in this episode.
