Ren and Dougie is part one of a three part crossover
Ren and Stimpy go to Bluffington were they meet Doug.
Stimpy: Ren, ha ha Ren I want a go on vacation.
Ren: Fine. It will have to be cheap. Wi'll go to Bluffington, the cheapest place on Earth.
Ren: Because it's so cheap, the animators couldn't afford a human color crayon.
(Ren and Stimpy arrive at Bluffington)
Stimpy: Great, now all we need is a room to rent.
Ren: By that you mean, break in to a hotel!
Stimpy: Hey there's one!
Ren: Stimpy, you moronic cat. That's a school.
Stimpy: But according to the billboard up there, there are no hotels.
Ren: fine. But it won't be as cool as breaking in to a hotel. Hopefully this school will have a hot tub so we can look at naked ladies.
(Ren and Stimpy break in to the school. Everyone runs away except Doug and Skeeter.)
Doug: Look Skeeter, and stupid cat and a hot head chuwawa.
Ren: You're not scared?
Skeeter: Dude, if you saw Porkchop, you would see our connection.
Stimpy: Ren, are these the naked ladies?
