Glenn Howerton is fucking amazing - great performance throughout. I still think Charlie edges it as my favourite character, but Dennis is possibly the funniest for being such a disturbing sociopath. Subtly, some of the pained expressions he pulls, in situations where his self-absorption is being tested, are heart-stoppingly funny. Not to say the rest of the cast aren't amazing.
I've been watching random episodes after quite a long break since the last episode aired. Even though I've seen pretty much every episode at least 3 times, they are still so fresh and incredibly funny. The Gang dances their asses off is one I had forgotten to be exceptionally good. I also really enjoyed Charlie and Mac die part 2 and The Waitress is getting married. One of my favourites though, is definitely The Gang give Frank an Intervention. The way it culminates in chaotic savagery is easily one of my favourite moments in television history. It's so typical of these characters' personalities, but there's something particularly scary and deluded about this one. Which makes it wholly hilarious.
Anyway, I will spare us all more comedic analysis.
"No, no of course we shouldn't bash these people up. Look, okay. Absolutely we could cave the husband's skull in here. Yes, we could take the wife in the basement and have a frenzy free-for-all with her! We could tie the kids up in their little rooms upstairs, so they wouldn't hear none of it."
