“Mark just moved here from San Francisco,” Knight gushed. “To clarify, we are not having a commitment ceremony and I am not performing a commitment ceremony.”
“Once you are given something that you were never allowed before, you realize how much of a second class person you were before. That is horrible and fantastic at the same time. It makes me want to sob and scream with joy all at the same time.”
“The floodgates have been opened they will never be closed,” Cornelsen added.

"Someone in particular, I won't mention names told me, 'You know I like him more than I like you, right?'" the actor, 35, joked. "They said it about three or four times so it's kind of not as funny as it was the first time anymore."
"They love him," Knight said. "They're like, 'When is he coming?' They want him there." (source)
