I feel you. My father has been suffering with this disease and related dementia for a few years now. He's gone through several stages till now where he's almost completely lost touch with reality. He constantly talks to the TV and himself. It's really sad when you think about it too much and realize the person you've grown up with and cared for all these years is basically dead and replaced by someone completely different whose personality is constantly changing. At this point, the humor is the only thing that keeps it from being too painful to watch. In his crazy ramblings he says some really funny shit, because it's just so random or so childlike coming from this grown ass man.

For example, my father was always really into sports and now it's one of the things he clings on to, but of course in demented and crazy ways. He wears a baseball glove almost all day, just walks around with it on, watches tv with it on. He seems to think he's on the Yankees and will tell us he needs to go to practice or tell the TV he's ready to be put in if he's watching them. He also has this weird obsession with Joe Torre (former manager who isn't even with the team for years now). The other day on the 4th there were a lot of fireworks going off around my house and of course my dad thinks we're in a war zone. He starts begging that the invaders "don't kill my people!" and asking where Joe Torre is, saying we need him to come save us (as if he's some badass super hero or something). Once the Joe Torre stuff came out while I'm trying to convince him it's just harmless fireworks and no one is going to die, I just lost it and start laughing. It's just so batshit crazy that you have to brush aside the depressing aspect of it and laugh at it.
