Paranoia Agent

I was watching Adult Swim last night, and there was this very interesting anime called Paranoia Agent on. I was web-surfing so I might have missed parts.

Basic gist (for the one episode I saw):
Four women meet outside an apartment building, three of them are middle-aged, and seem to be rather close friends. The fourth was hanging on, trying to fit in. They were exchanging stories about the source of this guy who's been going around clubbing people with a baseball bat.

[story 1]
A mother is living with/visiting her son and his wife. The son is at work. The mother is upset with his wife for not being a traditional Japanese wife, and decides to instruct her on proper behaviour. After a little while the wife is completely fed up. She grabs a wood cooking utensil and glowers at the mother. The doorbell rings. Mother and wife both run to the door screaming 'Toshi' for their son/husband. Door opens, and its Li'l Slugger, on roller skates and brandishing a semi-broken baseball bat.

[story 2]
Its a baseball game. The pitcher is not doing well, late in the game. He goes to pitch, and there at the plate is Li'l Slugger.

At this point the fourth woman claims that that couldn't have happened because everyone would have known about it. The three women friends close ranks and all agree that they know the story because they were at the game.

[story 3 - this one made the least sense to me]
A woman is pregnant. She had been about to try in-vitro, but then she got pregnant. The assistants in the doctors office are telling the doctor that the woman was impregnated with the wrong fertilized egg (didn't get where the wrong egg came from). The doctor tells the assistants that they are not going to reveal to the woman that the embryo is not hers. The woman goes home happy. A few months later she's back complaining about severe pain from the pregnancy. The doctor is in a visible sweat, saying that everything's ok because its her baby. He pulls up the ultrasound and inside the woman is Li'l Slugger, complete with roller skates and broken baseball bat.

The three women say that the fourth woman made the story up and it wasn't a good story anyways.

The fourth woman goes home. She opens the door. Her husband is lying on the floor, bleeding profusely. She becomes excited and asks him 'how did this happen'. He responds: 'Slugger. Call an ambulance'. She asks again, 'No, tell me how he did this.' Her husband seems to fall unconscious.

I think there was another story in there but I cannot remember it. But I have to admit I am intrigued by this program.
