I just got done marathoning all the episodes of this series, and god damn. This is, hands down, the funniest show on television right now. Every cast member brings something fresh and hysterical to the program, and the writing is every bit as tight as Arrested Development or Seinfeld in its heyday. Plus, the interactions between Dennis, Mac, and Charlie are eerily similar to the interactions I have with my friends. Please, please tell me I'm not the only one watching this unbelieveably awesome show right now.
And to those not watching, DL as many of these episodes as you can possibly lay your hands on.
EDIT: From the episode where they coach a children's basketball team.
Dennis: *to little kid* Okay. These are for you. Now there's a steel toe in there, don't be afraid to use it on whoever has the ball.
Kid: Thanks, Dad!
Dennis: *immediately* I'm not your dad.
