Is there a good "atheism" episode of a TV show?

There are multiple episodes of 'House MD' that deal with religion. There are a couple of Atheist characters on the show, and there are numerous references to Atheism throughout the series.
Here are the episodes that more specifically discuss religion:
1x5 'Damned If You Do'
2x19 'House VS God'
3x24 'Human Error' (sort of)
4x03 '97 Seconds' (sort of)
5x15 'Unfaithful'
7x08 'Small Sacrifices'

I wouldn't say that any of these is an "atheist" episode. But atheist characters are forced to confront religion in one way or another.

I'm pretty sure that there is a 'Boston Legal' episode or two that deals with atheism in the context of religious arguments, but I can't quite remember... I also suggest episode 3x03 'Dope & Faith' of American Dad, which deals with Stan becoming best friends with a guy until he finds out that guy is an Atheist... Both American Dad and Family Guy have heavy Atheist influences.

I don't think I've ever seen any tv show deal directly and specifically with atheism for an entire episode, especially since Atheism isn't really a unified belief system (except for the 'no gods' thing).

i've never heard of one, so no. then again, considering where some people stand with atheism, should we have a full episode dealing with atheism on TV?

It's not exactly a shining example, but the episode of Glee 'Grilled Cheesus'... There are a lot of religious things in the episode, but I really liked how they made Kurt keep his beliefs (atheism) rather than "seeing the error of his ways and finding god"
