WMG: It's Always Sunny in Philadelphia

Charlie is Charlie Gordon.

The following will spoil the ending of Flowers for Algernon.

Think about it. At the end of Flowers for Algernon, Charlie moved out of New York. Since this was an attempt to move somewhere where people didn't know him, he may have changed his last name to Kelly. He then got a job at Paddy's Pub (also cleaning), and he kills rats because they remind him of what he can remember of Algernon. He didn't remember his parents, so he probably met up with his "mother", who thinks Charlie is her real son because she's, well, crazy. Since Charlie's memory was decreasing, everything said about his past in the show was probably just made up by him, and everybody in the show plays along out of pity. The most clear evidence of this theory are Charlie's impossibly bad spelling, not to mention the fact that he's already borderline retarded.
  • They did a Flowers for Algernon parody in season 9 with Charlie. The treatment was actually an experiment to see how he and the gang would react if Charlie thought he had become smarter.

The finale will be exceedingly dark and humorless and will be about the group realizing that Dennis is a serial killer
  • Or, it will be the funniest episode. The gang will still realize Dennis is a serial killer, though.
    • Is there something to back this up or is this just REALLY Wild Mass Guesing?
    • It's more about the "IMPLICATION"
      • Dennis being an implied serial killer is somewhat of a running gag on the show, and it's been hinted at repeatedly, especially in the season finale of season seven.

The Gang's flanderization is a result of their deteriorating mental health.

Green Man is Charlie's "safe" persona created to cope with being molested
  • Charlie mentions that being "Green Man" got him through vaguely reference some rough times. Like say, being molested by his uncle.

Dennis is a reincarnation of Patrick Bateman.
  • He's a complete sociopath, a controlling neat freak, a witty deadpan snarker, and an implied serial killer. He even has the taste for eighties music.

The finale will have the whole gang die.
  • The McPoyles will come back for one last revenge scheme, and as they kill the gang, also end up killing themselves. Then Rickey Cricket comes out of nowhere and thinks it's a sign from God, only to have something fall and kill him too.

The Waitress' name is Nicki Potnick.
  • We know Nicki is a girl and Frank took her nametag. We know the Waitress couldn't find hers. The fact that the Gang knows of Nicki and apparently hung out with her in high school would be utterly in character with their forgetfulness of... everything about the Waitress.
    • Jossed in a Tweet from Glenn Howerton.

Mac isn't really gay. He's just confused and the writers are just messing with us
  • I think people on message boards started to pick up ambiguously gay cues with Mac and the writers decided to hint more strongly at it just for fun
"the thing is, I kind of hate women"

The gang will eventually kill Cricket
  • And they'll make sure someone else is blamed for it.

The reason Mac's become more and more gay is because...
...he finds it harder and harder to deny who he truly is to himself and those around, but is afraid to come out which is why he's also more homophobic. Think about it. In the first couple of seasons, Mac came off as straight. Then Mac becomes Ambiguously Gay with hints of homophobia. Though it wasn't to the extent it is now. Now he's so homophobic that he says AIDs is God's punishment for gay sex and not even fooling anyone into thinking he's straight. He could be so homophobic yet less ambiguous because he wants to avoid being gay or outed as gay, but he just can't hide it anymore. So he just resorts to prejudice and calls it a day.

Dennis and Dee will make out.
  • And Dennis will enjoy it.
    • If they do canonize Dee/Dennis, I have some theories on how this will play out:
      • The McPoyles approve, this creeps Dennis and Dee out.
      • Or they play up Dee and Dennis' disgust at the McPoyles and their incestuous relations for Hypocritical Humor.
      • Given his screwed views on consent, Dennis might force himself on Dee. I'm not so sure about this one though. I know they've done Black Comedy Rape jokes. But they never actually show it. So this one might be too dark even for this show. And even if it isn't, it could cross Dude, Not Funny! territory.
      • It is awkward (because y'know, it's taboo and all) and Dee and Dennis never speak of it again. Or if they do, it's really awkward.
      • They become an Official Couple and their relationship is terrible, but may stay together anyway because they can't do any better.
      • The rest of gang make fun of Dennis or at least, are confused by this because not only did he make out with his sister, but also because Dee.
      • Someone takes a picture of or video tapes them making out and blackmails them with it.
      • They were drunk.

Mac subconsciously wanted to ship Murtaugh/Riggs in the ''Lethal Weapon" Fan Films.
  • The Shower Scene between Riggs and Murtaugh. Okay, the reason why he put that scene in there was obvious. But listen to him defend the scene, saying it's a love story between two men. It's clear what he meant. But it's also portrayed as a partial Freudian Slip. Why not take it a step further and think he actually wanted the Token Romance to be between Riggs and Murtaugh?
  • In Lethal Weapon 5, the Police Chief tells Murtaugh his wife is dead. At first, this seems like it's for dramatic purposes. But think about it. His wife dying also makes him single which gives him and Riggs the opportunity to get together romantically.
  • Riggs marries Murtaugh's daughter. This is a bit of a stretch, but he could have shipped them (or been okay with shipping them) because she resembles Murtaugh and it's closest to shipping Murtaugh and Riggs, he'd be able to live with.

The series finale will involve a Kill 'em All ending
  • Either the gang dies at the hands of those they have wronged throughout the seasons or the gang will snap and kill eachother.

Mac isn't gay, he's bisexual. The Gang just can only think in absolutes.
  • He's a got a fetish for older women, at the very least. But the gang is so ignorant that the idea of anyone being something other than gay or straight is a totally alien concept to them.
