Quote from Barney in The Ashtray
Ted: You know what, Barney? Now that I think about it, you were there. Robin: That's right, you were. Barney: I was? Robin: Yeah. Barney: I mean, I know I was. That's what I'm saying, guys. Ted: We just... We just didn't realize it because you were in disguise. Robin: Yeah, you were doing one of your plays from the playbook. Ted: On Shelly, the art consultant. Robin: Yes, it was some play that had to do with art... Barney: The Royal Archduke of Grand Fenwick? A simple play you can do using two everyday household objects: a Prussian military costume and an oil painting of yourself? Robin: That's the one, and it worked on Shelly. Barney: I totally nailed her! And then I nailed her sister who was even hotter. [high fives Ted] Oh, good times.
