I am such a nerd

So I was listening to CNBC (on XM radio) on my way home from work last night. The show I was listening to is called Fast Money. I forget what stock there traders and the host were talking about, but I remember that one of the traders said that he still liked the stock. This trader suggested that people buy the $20 call option and sell the $22 put option; to which the host made fun of the trader for the complex trade (it isn't too complex, but, rather, more complex than the general public likes) and said, "Where did that trade come from, Chicago?" I laughed at that one, because I understood the implied joke.

Like I said, I'm a nerd.
