6. The Wayward-Rachel-Enlightenment Tour

Though it sometimes got to be a little bit too much, the Wayward-Rachel-Enlightenment tour was one of the season's crown achievements and the series' crown improvements. A Rachel (Lake Bell) with her head on straight, with a boring job and a boring boyfriend, is, well, boring. A Rachel who's adrift, gets into hilarious situations like her shroom incident, and stirs up good drama by hopping in the sack with Ben's dude Domingo (Kid Cudi), thus freeing Ben up to pursue other women like Nancy Frankenburg (Gina Gershon), is very fun to watch.
