Future Ted reveals that when he and Robin were dating they had a private joke where they would salute whenever another person used a military rank before another in a sentence (an example being 'Major Payraise'), but since breaking up simply share awkward looks whenever someone does it. Later, over the dinner Bob used the phrase 'Major Buzzkill', causing Ted and Robin to salute without thinking. As everyone tidies up from the dinner Ted notes there's going to be a 'major clean-up' making everyone unknowingly salute. They end up wondering if they'll be doing it all the time, which Robin responds with it being the "general idea," making everyone salute again.
