I don't think any of these couples really has a long shelf life. Of the choices, if I had to pick, I'd say Jim and Jenny, followed by Nick and Vanessa.

I say Jim and Jenny.

I said jim and jenny. There both older and have had marrages so they know what they want.

Of those.. Jim and Jenny probably have the biggest chance to survive I'd say.

I voted Jenny and Jim.

Jim and Jenny

Jim and Jenny but I voted Vanessa and Nick

I have to go with Jim and Jenny. They're the only ones up there who look to be genuinely enjoying eachothers' company. Here's my theory (it won't be silly, I promise. Man, how odd that I have to PROMISE not to be a smartass?)...

John & Jess: she's on the rebound, obviously. She's walking in front of him. He's looking at the ground with his hands in his pockets. The body language is a dead-giveaway.

Nick & Vanessa: Hamming it up for the camera. If their faces were squashed any further one might just end up inhaling the other (okay, MINOR joke, gimme a break).

AM & Mandy: Check out that body language, man! They both look miserable! He looks pissed, she looks like she wants nothing to do with him. Why are they even together? (BTW, I like her shades).

Joel & Nicole: You can tell he's a possessive guy. And her...well, what I can see of her...she looks like she's gonna keel over. Maybe it's his B.O. (okay, another minor joke, sue me).

Jim & Jess

None of the Above.

I voted Nicole and Joel...waddo I know

I said Nick and Vanessa...but I don't think any of them will last "forever".

I say Nick and Vanessa....the rest....not so much.

Vanessa and Nick.

Jimmy and Jenny
