Let us not be hasty here. In this hypothetical situation, one has to assume that you're not going to be having sex with random strangers 24/7, no? So, in that case, you'll need people that seem down-to-Earth and that can hold their own in conversation.
That being said, I'm starting with dudes because I'm not real keen on "guy talk" with chicks, if you know what I mean. I mean, I'm probably not going to talk about Notre Dame football with Tiffany Taylor...
1. Ron Jeremy. Dude seemed pretty clowning on The Surreal Life. He probably has some great stories. I mean, he knew fuckin' Rick James! Plus he's like a super-Jew, so assuming we're trapped in said room, I have to believe his can MacGuyver our way out.
2. Lex Steele. Gotta have an "urban" perspective in the discussion pool!
Now, if we're just picking pornstars based on attractiveness, I'll still lean more towards the ones that don't seem as smart as a velcro shoe.
3. Julia Bond. She's cute but she's not make-you-stupid hot. Plus, she has flaws, so she shouldn't have a big head. She seems semi-intelligent and is into some shit like DJing and rap music. So, at least she has SOME sort of personality.
The rest would just be random chicks stranded in there that were hot and hopefully able to form sentences:
4. Tiffany Taylor
5. Eva Angelina
6. Jenna Haze
7. Penny Flame
8. Natasha Nice
9. Naudia Nyce
10. Vicky Vette. I have no clue who she is but she "attention whored" a couple posts up and I can't think of anyone else anyway.
I think I thought too much about this mindless thread...
