These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Acceptable Lifestyle Targets: Hippies in the early song "Hippie Smell". Interesting in retrospect because 1) their live performances eventually started to make them somewhat popular with fans of jam bands, and 2) they also have "So Long Jerry", a completely sincere tribute to Jerry Garcia.
The At the Cat's Cradle DVD performance of "The Going Gets Tough from the Getgo" has a couple. For one, there's Gener's priceless facial expressions after flubbing the lyrics by trying to begin the verse instead of repeating the chorus, a mistake he makes several times in a row. More amusingly, though, there's Dean Ween's ad-libbed line that comes completely out of left field: "Stick it between my titties, Gener, and make me cum!"
Speaking of Dean's live adlibs, there's also the version of "The Blarney Stone" on their Live in Chicago DVD. This rendition of the song features an improvised verse that arguably has some of their most audacious lines ever, such as "I got cancer in me crack / I've got tumors on me nutsack."
Face of the Band: While they've had a fairly consistent backing band since adding one to their sound, Dean and Gene tend to be more widely known. Among non-fans, Dean is probably slightly more well-known for his occasional session work, such as playing on Songs for the Deaf by Queens of the Stone Age.
Growing the Beard: Whether you prefer their early "brown" albums, Chocolate and Cheese and beyond, or all of it, their early independent albums they recorded as teens are universally regarded as worse than their major label releases.
Magnum Opus: Many fans and critics - and even Dean and Gene, themselves - consider The Mollusk theirs.
Older Than They Think: The vocals in "Push th' Little Daisies" - especially during the last verse - are sometimes described as an Eric Cartman impression despite the song being recorded years before the first episode of South Park aired.
Vindicated by History: Quebec. It wasn't well-received on its' initial release and polarised the fanbase for its overtly prog-rock sound and more serious-than-usual subject matter, brought upon by Gener's divorce and Claude Coleman's car accident (Dean Ween would go on to describe the record as having a Jonestown vibe). Response to the album has become much more positive in recent times, with Stereogum declaring it in 2012 to be the best Ween album.
