Torn between Charlie or Dee.

It's gotta be Dennis for me. I love how his character has evolved from normal guy, to slightly egotistical, to full blown psychopath. However I they've toned him down a bit this season and he seems to be getting more normal. Also Glenn Howerton's acting is just incredible (that scene where he stares at the police monitor is so creepy).

Charlie :)

Charlie is great in small doses, as is the same for Frank. Their weirdness loses credibility with longer exposure. That last episode with the worm was... very odd.

Mac or Dennis is the best character, because both characters are the only ones with reality in mind; they can be portrayed as unintelligent or intelligent for whichever the situation requires, dispensing out common sense or absurdity.

agree that Charlie is best for short periods. Kinda TOO over the top at times. Mac is the best imo. Hes the most versatile and not overwhelming like the others.

Dennis, hands down.

Dee for Deandra.

Dennis. In the earlier seasons he was hilarious when he was aware of the crazy things the other members of the group did/said. Then Flanderization happened.
