One that recently crept from the back of my brain to the front recently is a cartoon from the mid 90s called "Waynehead." It's a short lived (only 13 episodes) cartoon series created by Damon Wayans that was inspired by his childhood in Manhattan (the title character was voiced by Orlando Brown, who prior to Waynehead was a child actor from Wayans' previous work on Major Payne, and nowadays would be best known for playing Eddie on That's So Raven). The "quick and dirty" description I'd give the show is you could call it "Hey Arnold with an almost all black cast of characters." It was first on Kids WB, but I remember it most from when Cartoon Network aired reruns of it semi-frequently from 1998-2000. One thing I certainly remember the best is the theme song, which I'd describe as "a very 90s sounding hip-hop tune."
(sorry for the super artifact'd video, this upload from 2006 is the only video I could find that's the theme song on it's own)
And the other show I feel is pretty forgotten nowadays is "Insomniac with Dave Attell." This was a show on Comedy Central in the early 00s where stand up comedian Dave Attell would walk around various American cities after performing shows at local comedy clubs in order to showcase the local nightlife. Most often he'd visit the local bars, chat with people who are out for a night on the town, and people who work assorted nightshift jobs like cow milkers, bicycle police, and even hookers. The series was popular enough to get 4 seasons and even specials taking place in cities outside of America (being the weeb I am my favorite was him visiting Tokyo), but despite this I rarely ever see people talk about this series as some "Comedy Central classic" like South Park, Drawn Together, The Daily Show with John Stewart, The Colbert Report, or Chappell's Show. I guess this could be because compared to other shows on the network it was a much more "laid back" series, but personally I've got a soft spot for it even if it has been years since I last saw it.
