Tex is upset that Lopez has wet the carpet in the living room. Lopez emphatically denies this, but Tex and Church, are convinced that it's a sign that Lopez is ready to potty train. However, it's actually Tucker who's wetting the house, and he tries to clean up another accident that night.
After a failed attempt by Church at getting Lopez to use the toilet, the family goes to the supermarket to buy groceries. In the checkout line, Tucker has another accident, revealing that Lopez (much to his own delight) is innocent. This leads to Tucker going to see Dr. Kaplan, a psychiatrist. The doctor decides Tucker is having a mid-life crisis, so Tucker goes travelling and exploring.
Tucker feels better, but shortly after returning, Lopez frames Tucker by peeing all over the living room. Tucker is blamed and returns to Dr. Kaplan to find out why this is still happening. After revealing that his last accident happened after watching Tex and Church have a water fight while washing the car, Dr. Kaplan causes Tucker to admit to himself that he is in love with Tex. Later Tucker sits next to her in the couch watching the news and "tries" to crack a joke, later to find out Lopez was watching the whole time blackmails him for it.
Tucker and Tex discuss the situation and decide to just remain friends. Church, who is unaware that Tucker's love is Tex, conjectures that Tucker's beloved would "probably end up with some idiot." The action oves to the Municipal Golf Course, where Church proves himself to be the idiot in question.
