Krystal Robinson sits near Park and 14th Street in Washington. She and Braddock were matched based on their answers to the <a target=\Date Lab questionnaire.

In her post-Date Lab interview, she said: “To me, it felt like a really good date. As far as a spark, there's definitely potential.” But although she and Braddock got together outside of the watchful eye of The Washington Post, she says the connection “just kind of fizzled away.”

Ammon and Duffy had fun on their date and both gave it a 5 out of 5. But while readers were toasting Armani’s matchmaking prowess, the couple never managed a second meeting. Today, Ammon is living the single life; here, she socializes with friends during Jazz in the Garden at the National Gallery of Art in Washington.

Duffy and Ammon’s is a common Date Lab experience. Though the daters often express interest in pursuing a second date outside of the newspaper spotlight, we later learn that complicated schedules, or a change of heart, or another burgeoning relationship cut their coupledom short.

And what about when Ammon and Duffy learned a monkey had matched them? “It’s almost completely random, which is how you meet someone a lot of times anyhow,” Duffy says now. Ammon felt, “a little surprised,” then “kind of stupid. Like I felt like the joke was on us, and I didn’t sign up for that.”
