Carter and O'Neill: Stargate SG1

I always loved the Carter and O'Neill chemistry on Stargates, one being a super intelligent agent and the other a very succesful military commandment. It made it real funny when he wanted to get technical information from Carter, and she went on explaining the details before giving the final conclusion which threw O'Neill to become more and more frustrated since he wanted answers fast and didn't had much patience for the technicalities.

Eventually on this scene he sort of snaps and well his facial expression is priceless. Before and after Carter explanation. He just look like saying What are they talking about?

Eventually he just said, cmon carter just say we can do this, cutting her short and saying, are you just going to tell me that we will be able to do this? just say we can do this.
