... is simply due to their constant drinking. It's actually pretty obvious - anyone drinking this much for this long is guaranteed to suffer some rather unpleasant effects. Some of effects this can have (according to Wikipedia) include impaired development, irritability, antisocial behaviour, depression, anxiety, panic, psychosis, hallucinations, delusions .. remind you of anyone? The way the Gang acts now, in the 11th season, is just the logical consequence after years and years of drinking. This show does have a Status Quo (the Gang can never suceed), but there's also a lot of character development, and since the gang never had to face reality because of Frank's "endless goddamn supply of money", his crazy, depraved antics ''plus'' their excessive consumption of alcohol ''plus'' the occasional drug habit, the showrunners are simply depicting the effects this behaviour had on these characters as straight-forward as possible. Which might also be the reason why the show recieves more and more criticism as the {{Flanderization}} continues - because watching a person fall apart due to the long-term effects of alcohol consumption simply ''isn't fun''. It might just be SeasonalRot, but it could also be an attempt to show that even though the Gangs weird antics and schemes are pretty fun to watch, their behaviour is seriously harmful to them and others. And even though the fans of the show can really appreciate really, really DarkComedy, there's a real chance there to make this show ''incredibly'' deep as well.

[[WMG: Frank didn't really understand Mac's dance at all]]

In season 16, after Mac says he has beads up his ass, Frank freaks out and says he doesn't get it anymore, citing that the dance didn't say anything about beads. Though it wasn't touched on further, this implies that the only reason Frank liked and understood the dance is because it was Mac dancing with a girl, and he didn't really take any deeper meaning from it.

This relationship will last longer and be more serious than the Gang expected. Yet, none of them will care too much about this new relationship... except for Dennis, who starts getting extremely jealous of this new guy because it means Mac is paying attention to someone other than him. Eventually, it'll all lead up to Dennis having a GreenEyedEpiphany and realizing he loves Mac. This will then create an UnrequitedLoveSwitcheroo, where instead of Mac pursuing Dennis like in Seasons 13 and 14, Dennis will be the one pining after Mac and trying to steal his attention, possibly even attempting to sabotage Mac's relationship. All the while, Mac will either be completely oblivious to this, or he'll [[SelectiveObliviousness pretend not to notice]].

Since Reynolds and Rob [=McElhenney=] have recently acquired a Welsh football club, there's some possibility that they can try and sneak him somewhere in a future season. He can play Mac's new boyfriend.

Another example of the show's reality-bending jokes (similar to Jack Bauer and Patches' immortality), the Dennis Doll came to life from the Gang's collective insanity and has become the ReplacementFlatCharacter so the Gang's equilibrium can be maintained. It's very suspect that the Doll completely disappeared, with Dennis in the exact same position it was in, and that he never explains what happened with the women and his child.
