5 for "Dirk Digital" (along with the MST3K auto-5)
i can't believe this isn't a dupe.
Also, i can't remember the specific episode (later sci-fi channel season), but Mike references "Kick, punch. It's all in your mind." from Parappa the Rapper, so at least one of the writers actually played the free PlayStations i'm sure they got for doing this.
For a while the Playstation site I wrote for was in competition with PSX Underground, or at least trying to be. All you really needed was a decent video capturing software and a modded PSX and you could do all sorts of "exclusives" from your parents' house. But we got bought by UGO and things went downhill from there.
