On paper, <a href="http://www.washingtonpost.com/wp-dyn/content/article/2010/05/28/AR2010052803398.html" TARGET="_blank">Daniel, 26, and Anna, 27, were looking good</a>: both dedicated marathoners who liked travel, didn't put much stock in material possessions and had great smiles. But there's always a risk; as Anna said, "Runners can be strange people, and I have met guy runners who are just bizarre." Fortunately, Daniel wasn't. She thought he was attractive from the get-go and was drawn to his laid-back manner; he called her "gorgeous" and "dynamic," and found her ability to move from wine to PBR charming. Things went just as well out of the Date Lab spotlight -- seven months later, they're still together.

Kajka, 37, and Kevin, 39, shared penchants for biking and traveling, and each said they had an adventurous side. But <a href="http://www.washingtonpost.com/wp-dyn/content/article/2010/04/15/AR2010041504997.html" TARGET="_blank">their date was doomed from the introduction</a> -- she's a hand-shaker, he's a hugger. Kajka was unamused by his garage band hobby, got uncomfortable when Kevin put his arm around her for a photo and wasn't feeling the physical chemistry. By the time they got on the Metro to head home, she'd mentally checked out: "There was a guy sitting down in front of us playing chess on his iPhone, and I was just staring at that because Kevin was talking and I wasn't listening anymore." Needless to say, there was no second date.

With karaoke, the potential for disaster is off the charts. But Todd and Lauren, both 26, <a href="http://www.washingtonpost.com/wp-dyn/content/article/2010/01/15/AR2010011503043.html" TARGET="_blank">threw caution and dignity to the wind</a> when they followed up dinner with a round of off-key warbling at Freddie's Beach Bar. A little kissing and a lot of liquid courage persuaded Todd to sing "Dust in the Wind" by Kansas; Lauren followed up with a rendition of Lady Gaga's "Poker Face." Despite the next morning's hangovers, we salute their willingness to risk embarrassment in front of strangers (and The Washington Post).

We're big fans of the classic dinner date, but the most interesting stuff tends to happen when our couples head to a second location. Some go to bars; others head for concerts or salsa dancing.

So when Jeremy mentioned some girls who dropped him after what had seemed like successful dates, Pier decided it was time to be honest. "I told him in the middle of the date that I did not know why we were put together," she said. "I thought, I don't want him to look at this when it's published and say, 'Pier did the same thing to me.'" They finished dinner and went their separate ways.

Other people. Some participants show up with a friend in tow (nothing like an "I wanted to make sure you weren't a serial killer" to get things off on the right foot?).

Joe was a good sport about the spying sisters and charmed all three (earning a smooch from Lisa, here.)
