The principal or someone is on the stand, and John is asking him in what way Nelle's father's delusion could be harmful. John's making his point pretty well until a little toy train rolls by.

Afterwards, John bitches out Nelle's father for bringing in the train. I guess the train wasn't as clever as John's water-pouring schtick or his cymbal-clashing monkey.

Next we see Daddy Claus's doctor on the stand. He claims that Nelle's father seems to have most of the symptoms of "schizophrenoform." That's like schizophrenia, but it only lasts for a little while. The good doctor tells us that Nelle's dad has suffered from this disorder during the holidays ever since his wife died. John ascertains that Mr. Nelle's Dad is not violent. The doctor says that his symptoms are increased generosity and kindness. "He's been more loving," testifies the MD. I wait for opposing counsel to object to such ridiculous, non-objective testimony, but they don't. Oh, well. Maybe I should register for that correspondence-course law degree program, after all. ["Hey, if Rosie O'Donnell can go to law school, you sure as hell can." -- Wing Chun] The doctor admits to the defense attorney that his patient's disorder isn't predictable. He reveals that one day last June, Nelle's dad thought he was Alvin of the popular '70s rock cover band Alvin and the Chipmunks. Nelle makes a face as if she just remembered leaving her oven on.

Ling sits in Ally's office and takes her turn at the "don't trust your man with his ex" spiel. Jamie shows up and Ling growls at her more than once. Ally literally shoves Ling out the door. Jamie allegedly just came by to make sure that it was okay with Ally that she go to the party. Ally acts all polite. Jamie is very wily and ascertains that Ally hasn't yet slept with Larry. I watch this and complain that any normal person would have told Jamie to mind her own freaking business. My dad points out that Ally doesn't want to do anything to jeopardize Larry's friendly relationship with Jamie, because he'll still want to see his son. I have to concede to my dad's good point. Don't worry, though; soon I will coax my dad over to the Ally-Hating Dark Side.

Later, Ally goes to Larry's office and complains long and loud about Jamie and her obvious plan to hook up with Larry again. Larry starts to call Jamie and tell her not to come. Ally backs down and tells Larry just to stay close to her. Larry wears a really ugly plaid jacket.
