Future Ted: [v.o.] When Robin moved out, there was a hole in my life in the shape of an empty bedroom. I filled it with a new hobby.
[As Ted barbecues meats in Robin's former bedroom, he imagines her standing next to him:]
Robin: [coughing] What are you doing in my old room?
Ted: This room being empty was bumming me out, so I decided to do something healthy that would take my mind off you.
Robin: Well, nothing says healthy like smoking 40 pounds of pork loin in an unventilated room while having an imaginary conversation with your ex.
Ted: Just for that, you're not getting any.
Robin: I'm not getting any? You're the one smoking your own meat. Ho!
