^Yep. It's a shame that they weren't quite able to work out that ER/Friends crossover. (George Clooney & one of the other actors from ER did play doctors on Friends but they weren't the same doctors since ER is set in Chicago and Friends takes place in New York.)
Noah Wile (Dr. Carter) and Doug Ross (Clooney) did show up in a first or second season episode of "Friends" as dates to Rachel and Monica, yep. I'm not sure if we're ever told their names but they were doctors in a local NYC hospital. Maybe Drs. Carter and Ross filled in at a NYC hospital that weekend?
