In addition to the above, I'll tell you what I've scored points with on multiple occasions; browsing MDConsult (or another similar service) for the notable recent abstracts. This only takes only 30-40 minutes a week, and not a week goes by that some article concerning a meat-and-potatoes IM issue isn't published in a major journal, and your attending has probably read it. (Not just stuff about your current patients, but articles on general IM issues that you'll probably see soon enough.) And here's what will happen: you're rounding on the latest rule-out MI admit, and your attending will say "Speaking of MI, anybody happen to catch the article in this week's New England Journal on stenting vs. thrombolytics..." and while everybody else on the team--your senior resident included--is staring at their shoes, you can say, "Yeah, the one that said blah blah blah...?" Attendings eat this up and it's something you can do low-key that doesn't make you look too much like a assclown gunner, which you should always avoid.
