And I would say Jim is iffy, as I could easily see him being incredibly irritating in real life just as easily as I can see him being likable.
I almost didn't put him there, but as someone who's prone to falling in love and being heartbroken, I think we'd have a lot in common. Plus, his biggest rival on the show is Dwight, but Jim on a few occasions has done things to help him, and I think that's admirable.
Creed would be cool to have some beers with, and listen to him tell stories, but he's also obviously insane, and doesn't seem to care about much besides himself (giving crappy Christmas gifts, getting Devin fired so he could save his own job, etc.).
I would definitely hang out with Creed. Most of it would likely consist of staring at him, mouth agape, but it would probably still be fun as hell.
