I like this game; it is often played with my friends. Sometimes with animals, which is weird. Ahem.
Bret, Jemaine and Murray
Marry: Murray - I need more graphs in my life. Plus "Marry" only needs a U to become Murray. Er, if you rearrange the letters as well.
Date: Jemaine - I'm a J-dogg too, so we could get matching t-shirts. Or something.
Dump: Bret - sorry, but I don't want my money covered with honey, Bret. Plus, beard rash from all the snogging

Dave, Eugene and Doug
Marry: Doug - educated, supportive and a harpist - what more does a heterosexual boy need in a fictional husband!
Date: Dave - he'd show me the cool places to hang out in NYC. Well, the cool places according to Dave. But I'd be happy with that.
Dump: Eugene. Cute but creepy.
Coco, Sally and Mel
Marry: Coco - I'd race the fastest animal, and read the boringest book.
Date: Sally - the only thing stopping her from being with me is that she doesn't want to be with me.
Dump: Mel. Cute but creepy.
Demetri, Todd and Ben
Marry: Demetri - I'd like to be his Important Thing.
Date: Todd - good with his hands.
Dump: Ben - too, er, actor-y.
Bryan PM, Greg and Jim
Marry: Greg - composed under pressure, supportive, just plain adoreable.
Date: Jim - I always find a healthy supply of questions to be helpful on dates.
Dump: Bryan - I wouldn't like to repeat myself and set him off on another Matrix-phobic incident...
Keitha, BrahBrah and Paula
Marry: Keitha - there's something appealing about the Aussie lady. Not sure what. But there you go.
Date: BrahBrah - she loves dogs, thats good enough for me.
Dump: Paula - I wouldn't want to upset Bryan by getting between them...
