I'm watching this on HBO and they cut out the line after Roy sleeps with his landlord and she says "What is it about sex that makes me have to crap? Pump 'n Dump. You really jarred something loose". They cut out the "Pump 'n Dump" part, which I thought was odd.
I don't get that, though. What they cut in that scene was so arbitrary. They left-in her saying, "What is it about good sex that makes me have to crap? You really jarred something loose, tiger." And she's still making the cunnilingus gesture with her tongue and fingers. How is any of that any less explicit than "pump-n-dump"? As Casey Kasem once said, "Ponderous, man. F[CENSORED]ing ponderous!"
What's happened is you've watched the R Rated DVD and HBO is running the theatrical PG-13 version. I just got through recording it because it was what I saw many times theatrically and was used to. All I had was the videotape recorded from Showtime that played this version and now I can get a good clean recording of the PG-13 one on to DVD-R thanks to HBO GO. The version in the theatre runs about 4 min. shorter and the edits make the film flow better and the gags work more effectively. I hate it when they alter the films when they come to DVD without a choice for the different versions. Yours is easier to get. Mine was just pure luck tonight.
