Barney: Robin, I came to the desk to get this.
Robin: Is that the key to our room?
Barney: It's the key to James's room.
[When Barney and Robin enter James's room, there are rose petals on the bed, a banner reading "Love is Awesome", and a large life-size cake of a naked black man and a naked white man holding each other's asses:]
Robin: Oh, my. What is that?
Barney: It's an erotic cake. I wanted to surprise them for their anniversary.
Robin: Is that... Is that James and Tom?
Barney: Mmm, caramel marzipan, chocolate marzipan.
Robin: I love chocolate marzipan.
Barney: So does Tom. Used to anyway.
Robin: This is, uh, absolutely the, uh... the weirdest thing anyone has ever done for their sibling. I love you so much.
