Before the gang from "Are You the One?" successfully went 10 for 10 and won $1 million for identifying their perfect partners, there were plenty of non-matches testing the waters with some good ol' fashioned hookups. Although one memorable couple has gotten engaged and even spawned -- Ethan and Amber are expecting a bundle of joy this December -- most didn't find love with their initial choices since, you know, science said they shouldn't be together from the get-go.

Regardless of their romantic failures, let's take a look back at all the unforgettable -- and endlessly entertaining -- couples who enjoyed a little paradise in the Boom Boom Room:

Chris and Shanley

There's so much to say about their emotionally charged relationship. They clicked instantaneously on the first night...

...but when they were the first to visit the Truth Booth, the couple discovered they weren't a match.

Regardless, they continued the physical element of their relationship -- and Shanley couldn't mask her sadness when Chris and Paige were a confirmed match.

Adam and Brittany

The flirtatious duo clicked on the second night, and from there on out, they had a tough time keeping their hands off each other. Ultimately, their romance fizzled, but they certainly had some "animalistic" encounters while it lasted. Watch them elaborate on their romps -- or how they "f**ked like porn stars," as Brittany so eloquently put it -- below:

John and Simone

Before entering the love shack, Simone couldn't help but marvel at how many people were getting it on around her. Well, that's what happens when a bunch of love-thirsty twentysomethings live together. While the fun-loving combo didn't seal the deal, they earned the distinction of being the first couple to make (some) use of the BBR.

Scali and Paige

A smooch during "Spin the Bottle" ignited sparks and the couple eventually spent some intimate time together, but there was tension when he went on a date with her BFF Kayla. After the blond beauty vented her frustrations, the New Yorker planted a big one on her to quiet her down. Unsurprisingly, the matchmaking tests proved they weren't compatible.

Ethan and Amber

The dream couple wasn't just among the show's first perfect matches, but the soon-to-be Mr. and Mrs. are also going to be parents! There are too many precious memories to recount, but the one below is a frontrunner:

TRUE. LOVE.
