In the Season 5 episode Girls Vs. Suits, perhaps the best episode in the entire series, Barney rips one of his beloved suits. He rushes through the streets of New York in a desperate attempt to bring his ripped suit to the only person who can save its life: His personal tailor, TV's Tim Gunn.

Gunn, best known for his work on Project Runway, plays the part like a surgeon who's failed to save a patient. He apologetically tells Barney that the suit won't make it, ripping dialogue straight from medical dramas. Gunn and Neil Patrick Harris play the scene totally straight, making it all the funnier.

Gunn returns in Season 9 as one of Barney's wedding guests and continues to delight with each line.
