Robin: Hey, um, should've mentioned this before, but, um, Ted and I prefer that our guests remain fully clothed in the public areas of the apartment. Been some complaints.
Kevin: Did Ted say something?
Robin: Oh, th- there's been some complaints. Not pointing any fingers or anything, but let's just keep those pants on, okay? Good talk.
Kevin: Well, if Ted said that, I've got something to complain about, too... Ted's nuts.
Robin: Okay, yes, Ted is a little neurotic, but I wouldn't say...
Kevin: No, no, no, I mean Ted's nuts.
[flashback to Ted walking through the living room as Kevin reads the paper. As Ted's bath robe flashes open, Kevin spills coffee on his pants. He stands up and pulls his pants down. Ted returns from the kitchen to see Kevin in his underwear.]
Robin: So what? It's his apartment.
Kevin: You're taking his side? Wait, this isn't one of those classic "You still have feelings for your ex-boyfriend, who's oddly also your roommate, which for the record I'm totally cool with, even though everybody tells me I've walked into a bear trap" things, is it?
