After learning a LOT of how dial-up worked back in the 90s. This is NOT how it worked at all, LMAO! I know this is just supposed to be funny, but i gotta hand it to the animators. They're actually is a Digital Impairment Learning sequence (DIL) signal in the handshake, and i can hear it's a two toned crescendo. Kudos to them. (And knowing this show aired in 2003-05. They did pretty good on that front)
I remember Monkey Dust was on TV here in australia very briefly. This sketch was used to advertise the show, presumably because it is literally the only "clean" joke in the entire run.
