Coupling is one of the funniest TV shows I've ever seen. I keep meaning to get it on DVD (well, the seasons with Jeff, anyway.) And yes, Bill and Charlie are totally Porn-Buddies! And OMG, can't you just see a Marauders Porn-Buddy fic? Hee!
I wonder what the Wizarding version of "Lesbian Spank Inferno" would be? *snerk*
Gawd, now I'm imagining that episode but with James and Lily. LOL!
