Rasslor from the Dial M For Monkey episode of the same name was voiced by Randy Savage. His last line in the episode was, naturally, "OH YEAAAH!".
Adored by the Network: Well not surprising considering it was one of Cartoon Network's first successful original animated series. But from 98-2001, it, along with Powerpuff Girls were the flagship shows of the network.
Banned Episode: "Rude Removal." Available from [adult swim]'s website for a brief period. You can find the "uncensored" version on Youtube, but the swear words are nothing more than the sounds of various other words spoken in the episode spliced up and combined together. In other words, it's not officially uncensored.
In fact, Hungary holds a reunion for the Sailor Moon cast: Dexter's first voice was Melvin; Dee Dee is Chibiusa; Dexter's first mom was Sailor Neptune; Mandark's first voice was Alan's second voice; and Dexter's second mom was Berthier, Karonite, Eugeal, Mimet, Telulu, Palla Palla, and Fisheye. Mandark's second voice is not Chad.
Keep Circulating the Tapes: Bits of the first season were released on a now out-of-print VHS tape, the same goes for a collection of Genndy's favorite episodes. "Ego Trip" was released only on VHS, and that's out of print as well. The first season did get an official DVD release, but it does not include the banned "Dial M for Monkey" cartoon "Barbequor". Thankfully, the entire series (sans "Barbequor" and "Dexter's Rude Removal") is available on iTunes, and the entire first and second seasons (again barring "Barbequor") are available on Netflix.
Missing Episode: "Dexter's Rude Removal", an episode the crew made for themselves as a joke which contained heavy use of profanity that not even Cartoon Network would find permissible. Before the end of 2012 it had been aired outside crew parties only once, at a Genndy Tartakovsky panel at a convention where they kicked out everyone under 18. [adult swim] released the episode for a brief period on YouTube.
