Mr. Pipe: (shocked) Hey! What are you people doing in my house?!
Stimpy: (singing as everybody leaves the mansion) When a body rolls a body, goin' out the door...
(Ren says grace right before dinner)
Ren: Dear lord let us not swim 30 minutes after dinner and please bless our intestines. Amen.
(Ren recites the etiquette for greeting people to dinner parties)
Ren: The second thing to remember when greeting guests is to honor them with a sweaty handshake. I found Turkish weightlifters work perfectly for sweaty palms!
(cut to a Turkish weightlifter as he is lifting weights and Ren comes into the picture to stick his hands into the guys armpits)
Ren: Thank you.
(Stimpy and Chuck come home after a night out)
Stimpy: Hey, Ren, we drank toilet water... and I liked it!
Ren: That's nice.
Chuck: Hey, look at this. it's our old College yearbook. Those were the days.
Ren: They sure were.
Chuck: Hey here's you, flyspeck. Ren is president of the flower arranging corps, captain of the underwater chess team, and treasurer of the spelunker's club. Wow what a winner.
(Ren's old friend, Chuck looks around Ren and Stimpy's house to find pink furniture and pink curtains)
Chuck: Hey, ah Hoek, you're gettin' kinda "dandy" in your old age.
