What's funny is that this block of shows: Community, Parks & Rec, and The Office all, IMHO, have one thing in common: they all have flashes of brilliance, and all have painfully un-funny characters.
Community has the painfully un-funny characted played by Chevy Chase (Pierce is the character's name). His character drags down the show. Parks & Rec has the painfully un-funny Leslie Knope (Amy Poehler). Her character tends to take away from great moments that come from Ron and Tom, and to a lesser extent, Andy. The Office has the painfully un-funny (at times, but way too often) Michael Scott. Date Mike last week was yet another example of Michael Scott not generating laughs from the audience and causing them (us) to cringe. Other times you are supposed to laugh at his misery, but he's so miserable it loses the comedic punch.
The other funny thing is that it is the most well known people on these shows who portray the painfully un-funny characters. I don't know if that is by design or it just turned out that way.
