9. Brooke – Denver – Season 18

The Southern Belle sported high heels while nursing a “sprained ankle”, bawled when a guy invited her bowling, and had a hard time dealing with Mother Nature of any kind. Bad luck considering their job was to lead kids through the Rocky Mountains. Brooke also flipped out constantly, unnecessarily and awesomely. For that, we love her.
Entertainment value: 8
Drama Caused: 7* (most of it was in her head however)
Cohabitate-ability: 4

8. Jon – L.A. – Season 2

Jon was the young buck from the country. His giant cowboy hat shielded him from a tumultuous early 90’s L.A. But his bumpkin-fish in a big pond storyline became endearing – as long as we muted the TV every time he sang.

7. Dan – Miami – Season 5

Speaking of endearing, was anything more adorable than when Miami’s flamboyant gay man Dan’s family came to visit and he took his mother rollerblading? Mix this big heart with his devious streak and sharp tongue and you got one of the more watchable seven strangers.

6. Heather – New York – Season 1

Heather B., the aspiring rapper from the original season, spoke her mind, but not in an alleged-throw-a-candlestick-way (she left that to other roommates). She had a good sense of humor – displayed best when she called people in the phone book at random to tell them she was going to Jamaica. And we’re still laughing about the time she fell while walking the dog.

5. The Entire Vegas Cast

This season of the Real World marked a turning point in the show. Suddenly, it went from finding out “what happens when people stop being polite” to what happens when people start drinking 24 hours a day and start getting naked. No doubt fueled by Vegas’s own lack of sense, the roommates’ personalities all seemed to blend together into one amazingly disastrous cocktail. Cheers!

Cohabitate-ability: Depends on how much you like to party.

4. Ruthie – Hawaii – Season 8

Did someone say party? We all love it when “producers have to intervene” and Ruthie and her drinking (and driving) brought it to a spectacularly dramatic level. (Being hauled away in an ambulance the first night is a great way to kick off the season). As the first bi-sexual roommate, she also added a new level of intrigue.
Entertainment value: 6
Drama Caused: 9
Cohabitate-ability: 9 (when she was sober), 4 (when she was drinking and smashing glasses).

3. Tonya – Chicago – Season 11

Before she was making enemies on the Challenges, she was passing kidney stones and hogging the phone line in Chicago. From hospital bills, to a nameless sugar daddy, to her roommates' growing annoyance (they sang songs about her when she wasn’t around), she was one great train wreck to watch.

2. Entire Seattle Cast – Season 7

Arguably the best season in the show’s history, this cast included the maniacal Stephen, who b*tch-slapped a female on national television (a resume builder, indeed), a secret forbidden romance between David and one of the show’s producer, one of the cooler jobs (radio DJ’s in Seattle during a peak-time in music history), roommate Irene basically going nuts (due or not due to her Lyme disease) and possibly the best shot in the history of television: A teddy bear floating in the bay.

1. Puck – San Francisco – Season 3

An obvious choice for #1 maybe. But the snot-rocket blowing, non-bathing, inconsiderate, arrested on Day 1, bike messenger may have invented the “voted off a reality show” concept. It was the first time the show managed to truly show just how terrifying living with a stranger could be.

And the worst?
We realize it can't be a house full on Tonyas, but these people were so boring it was painful. We'd have preferred it if they were not 'picked to live in a house and have their lives taped.'

1. Jaime – New Orleans – Season 9

He had his act together and was smart – which gets you on your high school honor roll but loses you in a reality TV show.

2. Matt – Hawaii – Season 8
(Not surprisingly, there's no picture of him to be found.)
Too weird to be cool, not weird enough to be interesting.

3. Jay – London – Season 4

The original Emo kid wrote a play and slept. And so did we every time he came on the screen.

4. Entire Sydney Cast

We know it aired – we just can’t remember anyone on it? Can you? Didn’t think so.

5. Hollywood Cast

Their job was to be an improv troupe. Head back to the drawing board MTV.
