Thom (and Carson to a lesser extent) suffer from breathing difficulties in Kevin's filthy apartment. This is not just because of the dust and general dirt, but because Kevin has a pet cat and Thom is allergic to cat hair.
Thom: You live in a dump like a crazy person. This is freaking me out.
Carson (on seeing a photo of Kevin's glamorous model girlfriend): I like long walks on the beach, leopard-print bikinis, and squalor.
Thom: It'll fit! Put the damn ring on!
Kevin: Gay guys rule!
Kyan (about Kevin's hair): His inspiration was Johnny Depp. (to Kevin) Were you high?
Carson (testing out her new married name): Matilda Downey. Jr.
Thom: Sounds like a drag queen with a drug problem.
Kyan(Holding a book entitled "Please Kill Me"): I think he wrote this book. He wrote this book after living here for a year.
Kyan: Do you think she'll say yes?
Thom: Hell no!
Kevin (asking Matilda's parents for her hand in marriage): ...and I'll be a wonderful husband until I'm dead.
Ted: It's a last supper clock. Wow.
Queer Eye's second wedding proposal.
