And Starring - And introducing Jon Lajoie. Only in season 1.
Amoral Attorney - Both Ruxin and Kevin; a rare example where a criminal prosecutor isn't really any better than his defense attorney counterpart.
Ruxin has become much more amoral since the first episode, while Kevin has been shown to be moral but incompetent.
In addition, Ruxin rarely works as a defense attorney (claiming to do an average of 3 criminal cases a year), usually working as a corporate attorney. He's still amoral, and works for the most amoral of clients (serving as part of BP's legal team during the 2010 oil spill).
Anything That Moves - Russell. Really the only thing he doesn't seem to be turned on by is Jenny.
Or anything period, like pretzels and bread.
Rafi also qualifies. For both the trope, and things Russell is turned on by.
Played with by Dirty Randy. He does seem to fit the trope, but now can only get turned on by thinking about drag racing with Korean teenagers.
Batman Gambit - Ruxin is very good at these. One particular incident involving knowing the size of Andre's little fatty by lying to Shiva by using his position as Commissioner to take her picture off of the trophy. However, it involves a full league vote to make a decision. Shiva found out after she told him, and Ruxin made no attempt to change their minds.
Believing Their Own Lies - Andre genuinely thinks he has clear hair enough to "comb" it when he is alone rather than accept being bald.
The Friend Nobody Likes - As mentioned below, not one person in the league likes or cares about Andre even the slightest bit.
Gainaxing - In episode two, "The Bounce Test", various circumstances force Ruxin to find a "porn loophole": an underwear website featuring video demonstrations of their products being used by well-endowed joggers.
Genius Ditz: Taco is fairly talented musically, but too wasted to do anything else. Additionally, when you consider how much he gets around despite his shortcomings, he must be a masterful pick-up artist.
Gilligan Cut - Kevin promises that he, Jenny, Ruxin, and Sofia won't talk about Pete and Meegan's breakup at dinner. Cut to...
Groin Attack - The "Scrote Squad" subplot from Curse of Shiva.
Happily Married- Kevin and Jenny, who never have ANY serious marital issues, and the only minor ones are fantasy football related.
Hate Sink- Andre is explicitly labeled one in universe and it is claimed that it keeps the league from destroying itself. As the show has progressed it has become increasingly clear that not one other member of the league likes or cares about him in the slightest and he kept around solely for this purpose.
Henpecked Husband- Ruxin and Pete, at first. Pete got divorced in season 1. Ruxin just stopped caring about his wife, and doesn't listen to her anymore.
Jerk Ass - Everyone to some extent, though Ruxin and Rafi are probably the worst.
Taco when he's sober.
Jerk with a Heart of Gold - While they all do some pretty awful things, all of the main characters are basically good people (except for Ruxin).
Karma Houdini - Though everyone gets away with things sometimes, like when Kevin lost his virginity to Shiva in Pete's mom's car, left the condom behind, and kept the incident a secret for years, only revealing the truth after Pete had returned the favor to the person he THOUGHT guilty of the offense, losing an amazing job offer in the process, Taco rarely receives any sort of comeuppance for his outrageous behavior. Possibly justified, as they are used to his antics and/or feel guilty over making him smoke pot when he was 8, turning him into the massive stoner he is today.
My Friends... and Zoidberg - A nonverbal example. After Ruxin wins the championship in the finale of season 2, he tussles with Andre for possession of the trophy. It ends up sailing off a fire escape and smashing through a car windshield. At that point, Pete arrives in the cop car he now drives, takes control of the situation, and whisks everyone away... except Ruxin, who they gleefully leave behind to deal with the furious owner of the car.
Before the season 3 draft, Ruxin beckons the rest of the league to Andre's balcony.
Ruxin: Gentlemen. Taco.
Noodle Incident - While never verbally mentioned, observant viewers can see that Taco has actually won the Shiva Bowl once. Due to his complete ineptitude at fantasy football, one can't help but wonder how this could have possibly happened.
Andre's hazing period.
Andre: You guys hazed me for like 2 weeks. I'm still finding pieces of squid all over my apartment.
No Social Skills - Andre, and then some. It's heavily implied the reason he never leaves the league is because these are literally the only people who will talk to him.
Obfuscating Stupidity - If Ruxin and Sofia's anniversary is any indication then Taco. He shot behind the scenes footage of their wedding and saved it for ten years so he could use it in what seems to be a very lengthy plan to incriminate and embarrass not only Ruxin, but Kevin, Andre, and Meegan as well, at an anniversary party he manipulated Ruxin into throwing in the first place. When his plan culminates in Ruxin having to eat a piece of wedding cake that had been thrown onto a bathroom floor, Ruxin calls him "an evil genius."
In an interview the Producers confirm Taco is far smarter than given credit.
Ever since the events between season 2 and 3, Taco has been shown to be far less clueless, much more deliberate in his actions and just flat out more intelligent.
Obnoxious In-Laws - Kevin and Taco's mother, who constantly judges Jenny and condescends to Kevin.
Once an Episode - It's fairly inevitable that something shown or mentioned in the first scene of an episode will play into the punchline at the climax.
One of the Boys - Jenny, though a somewhat unusual example—she's not really a tomboy and certainly is feminine. She's just really good at fantasy football and can engage with and challenge the guys on their own terms. She also seems more comfortable with the boys than with Sofia, who she finds irritating, though notably Sofia is the only female (other than her own daughter) that viewers see her interacting with on even a semi-regular basis.
Really Gets Around - Taco has had sex with enough women to spend months successfully traveling around the world depending entirely on his international Eskimo brother network.
Running Gag - Shivablasting, Eskimo brothers, Andre looking like Nosferatu, vinegar strokes and Mr. Mcgibletts.
Something Completely Different - The episode "Rafi and Dirty Randy". The League suddenly becomes a stoner crime comedy starring Rafi and Dirty Randy as they try to solve the murder of their friend. About three quarters of the way through, they kill their favorite porn producer, become the owners of his mansion, and Dirty Randy ends up shooting Rafi in an insane duel. The whole thing is treated comedically, and hardly features any of the main cast members.
Sports Widow - Sofia knows to leave Ruxin alone when he and the rest of the league show up to watch. Averted by Kevin and Jenny: she's a bigger football fan (and better team owner) than he is.
Most of them revolve around some comically bad business idea or invention.
One of those ideas, "Neckflix," or "Netflix for Ties" becomes Life Imitates Art when the same concept was advertised as "Tietry" on Dragon's Den.
With Friends Like These... - Even without the constant volleys of insults and pranks, every single member of the League will manipulate and betray any other member for even the slightest of advantages in their fantasy football tournament. Except for Taco, who is to stoned to know what manipulate means.
One episode has Pete tell his friends that they're the worst people he knows. They take this in stride
