Marshall and Lily try to go on double dates with Robin and Barney, much to their chagrin. Ted becomes, as Barney describes, a guy who allows girls to stay at his apartment overnight without sleeping with them.
This episode provides examples of:
- Dirty Old Man: A perfect example of a Double Subversion. Robin talks about an older professor she had who she thought was attractive until he went to jail... for tax evasion. She laughs off the fact that everyone assumed something worse, but then she mumbles under her breath that he was also arrested for... other reasons...
- Nice Job Breaking It, Hero!: After Ted brags about how awesome being single is, what was Barney's response? "What have I done?!"
- Retraux: Barney's "Sexless Innkeeper" poem is presented as though the events take place in the 19th century. When Ted questions why there's horse drawn carriages instead of cars, Barney tells him he's doing it to match the poem's prose style.
