One Flew Over the Kai-Kai's Nest

S1, E12: Anthony and Joe become concerned when Tuga invents an imaginary friend named Kai-Kai and even blames Kai-Kai when a flowerpot is broken. When the men visit a child psychologist, Dr. Harvey (FRENCH STEWART - "3rd Rock from the Sun"), they learn that the problem may be with them rather than Tuga. They agree to stop arguing so much and write their feelings in journals, so Tuga will not feel so stressed in his own home that he has to make up a pretend pal. Even the journals become a source of competition between Anthony and Joe, until Anthony steals Joe's and reads that the reason Joe was reluctant to let Anthony move back in was because he is worried about losing him again. The guys reconcile--before discovering that shy Kai-Kai (LYNDON KARP) is actually a real boy.
