These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Charlie trying to rape his ex-wife is one of the more hilarious examples.
"Funny Aneurysm" Moment: The third episode features a porn star who asks Hank if she should get breast implants, even though he points out that her breasts are fantastic. The character was played by actual porn star Brooke Banner, who though famous for her natural breasts, went on to get implants a few years later.
Ho Yay: Hank and Charlie have some discussion of this in season three, although it never gets past the comfortable joking around stage.
They do cross into that territory a lot though, such as Charlie complementing Hank's penis size.
Richard Bates and Hank. Although Hank doesn't really reciprocate, he doesn't protest (not even when Bates kissed him in season 6) because he finds Bates so amusing.
Man Child : To varying degrees, most of the men in the show—despite tremendous career success—are drunk and irresponsible without much care or consequence.
Marty Stu: Hank. Seriously, a woman-hunting, hard-drinking, successful writer who somehow always comes out on top? This is a male writer's fantasy life.
Tear Jerker : Could also double as Crowning Momentof Heartwarming. In the season 2 finale, the opening scene as Hank finishes typing his manuscript with Warren Zevon on the stereo Ashby appears, converses briefly, then says "It's true what they say. Got a hell of a band." Then he disappears and we find out he did OD.
The Scrappy: Season 4 has seen a marked downturn in the ability of the audience to tolerate Becca's whining, monotone and flat character and an annoying sub-plot involving a bunch of just as annoying try-hard 'bad chicks' and their garage band. Check out the IMDB forum for one place where this crops up as a Base Breaker topic.
The Woobie: Oh Becca, why can't you find a Nice Guy to have a sweet, non-overly sexual, first/second relationship with?
