[When Ted arrives back in the apartment, Barney is carrying out bags of trash]
Ted: What are you doing?
Barney: Oh, well, since all these roomie squabbles are still causing friction between you and Robin, I thought I'd help out. Oh, BTW, I went by the post office today. I picked you up some stamps. Here's ten thousand. That oughta do.
Ted: Oh. Thanks, I guess. You want a beer? [opens the fridge] Whoa!
Barney: Yeah, I picked those up on the way over. It was nothing.
Ted: Did you buy us a dishwasher?
Barney: No. That dishwasher's always been there. How long have you lived here? [removes tag from the dishwasher]
