Marshall: What do you mean, "No, thanks"? Ted, you would be a great professor, OK? You are knowledgeable, you're a good talker, and when you need to, you can grow a very handsome neck beard.

[Barney and Marshall mutter]
Ted: Hey, hey, hey. Small business owner. Backbone of the economy. I'm not gonna take that job, all right? I'm gonna be just fine.
