When asked about whether or not she has a pet peeve regarding her new fiance, Becca was quick to respond: "He snores so dang loud, and he likes to call it 'purring'."
But that was not all, as she clearly had been thinking about all the annoying things he does. "He does this thing… where he loves paper towels, but he leaves them all around the house," she said animatedly. "So everywhere I go it's like a crumpled paper towel here, and crumpled paper towel there. So I've started [sending] him videos all day long."
Her new man, however, claimed to not have a single pet peeve regarding his fiancee.
But for viewers who have been tracking the strange odyssey of this past season's "Bachelorette" the elephant in the room -- and the real pet peeve most viewers had with Garrett -- was his habit of liking offensive posts on social media.
Garrett found himself in the middle of an Internet firestorm, when it was discovered he liked sexist, transphobic and anti-immigrant posts, as well as ones mocking Parkland shooting survivors, on Instagram.
The winner of this season's "Bachelorette," however, did bring up the scandal during "After the Final Rose" special on Monday. "Some stuff came out about my social media, and I didn't realize the effect behind a double tap or a like on Instagram. I put out an apology, I didn't mean to offend anybody, I apologize for that still," he said.
"I'm very sorry, I didn't meant to hurt anybody's feelings. I stand by everything that I posted in my apology, and I'm just trying to grow as a person be a better person on a daily basis," he continued. "She's helping me through everything, we've been honest, open and transparent with each other since the beginning. When that all came out, we attacked it. I feel like when I was liking things, it was going against what she stands for and that made it really hard on us as a couple. So when we started talking about that, we got through that together and we're growing, we're progressing and we're moving forward."
Meanwhile, Kimmel continued to keep things light and fluffy and only pitched softball questions at the couple during a game of "Fiance My Name," similar to the "The Newlywed Game," except a prequel edition.
During the quiz, Garrett and Becca were asked questions about their significant other to win prizes, such as their partner's middle name, the name of a grandparent, a pet's name, and the name of their high school, the latter proving to be the most difficult question. They both had absolutely no idea.
Becca guessed "Manteca High," to which Kimmel asked, "that means lard in Spanish doesn't it?"
"Yes, it does," Garrett joked back. (FYI "manteca" actually translates to butter, but close enough Garrett.)
For Becca, Garrett wrote that his new bride-to-be went to "Minnesota High." Obviously, that wasn't the answer. However, Becca really wanted the gravy boat prize.
"If I say yes, can I get the gravy boat?" she joked.
Overall, the couple won a good deal of swag from the late-night host, including a dinner tableware set, a melon baller, and a panini press.
Kimmel gave the couple an additional prize by giving them Costco membership cards, because they've always wanted to go shopping to the superstore together.
