Bathtime is the forty-second Simpsons short which originally aired on The Tracey Ullman Show on March 19, 1989. It is a part of the third season of the shorts.
When Homer calls Bart for his Sunday night bath, Bart doesn't want to take one so he hides in the closet. Homer hears him burp in the closet so he opens the door and takes him to the bathroom. He puts him in freezing cold water so Bart turns the hot water on the fill the tub. He then dives under and pretends to be a famous diver, complete with a French accent. He then realizes he left the water on and it floods the bathroom. Homer hears Bart crying for help, and opens the door, letting all the water out. He then starts to chase the naked Bart around the house.
