How I Met Your Mother Barneys Ode to Bimbos

I chose Barney Stinson's "Bimbo Monologue" as an example of a rhetorical situation. In this scene Lily confronts Barney on his womanizing ways and tells him that he will eventually have to settle down and that if he had to choose, which would he rather have, true unfailing love? Or bimbos? ^ (Video above) is his response...
His rant has the three distinct parts of a rhetorical situation: The exigence, audience, and constraints. The exigence, or the problem that calls for a solution, is Barney's choice for bimbos over an actual adult relationship. He trying to show Lily why he chooses the women he does and why he treats them with little respect. Despite his passionate speech, Lily of course still sees him as the slime ball he is and is even more convinced to change him.
Barney's audience is not only Lily who is in the scene with him but it is also the many viewers that this popular show has. Because Lily is clearly not even buying Barneys excuses, it is lucky that he has a diverse viewing audience that accept his speech as him "just being Barney".
Some obvious constraints that Niel (Barney) faces is that he can't go off on a tangent. He not only has a scripted speech that was written for him but there are also other scenes that need to be filmed. Also Lily can be considered a constraint because it is key in a rhetorical situation to have a responsive audience, and Lily and him clearly have different views on how to treat women.
I think the audience is a significant factor in this rhetorical situation, as shown in the clip, if you don't have an audience that slightly agrees with you or has the chance to be swayed or learn something from this speech, then you can't go anywhere. Barney is very eloquent and he puts emotion into his reasoning for his sexual preferences but all Lily needs to here is the word "Bimbo" and she is instantly tuning him out.
In any speech you need to have if not something in common with your audience, than an audience with an open mind. You would not have very successful results if you were to go into the Amish country preaching the benefits of technology of our daily lives. They have already expressed their adamant opinions against it.
