 Infobox cast list/billing 

I've noticed that the order of the cast list has been changed several times in the past few weeks, mostly moving Patrick Dempsey and/or Isaiah Washington higher in the list.  I'm guessing that this has been done based on perceived importance in the castobviously those two names are frequently in the press and PD's ""McDreamy"" is a huge pop culture thing and it could be argued that PD/Ellen Pompeo and IW/Sandra Oh are the two ""big"" couples on the show, but that has nothing to do with the order of billingnor is the placement of IW and PD at the bottom of the list someone's idea of belittling their roles on the show.  I double-checked the order with the most recently aired episode, and based on that I switched T.R. and Justin Chambers, as well as JP, Jr. and Kate Walsh.  The credits read, ""with Isaiah Washington and Patrick Dempsey""that final billing with the preposition ""with"" is actually a good thing, it reflects upon the actors' value to the show.  I just wanted to add this explanation here so that it could be referenced in case anyone was moved around in the order againmy edit places them in the correct order, as billed.  "
