Which episode of Scrubs is it when JD and Turk are bar tending and mixing cocktails?

Question by Magic 8ball: Which episode of Scrubs is it when JD and Turk are bar tending and mixing cocktails?
I’ve seen every episode of scrubs so many times that they’ve all sort of rolled into one. I can just very clearly remember this scene where JD and Turk are behind the bar making cocktails together in unison. The only flair trick I can remember them doing is picking up the bottles, moving them behind their heads and pouring together.

If anyone can remember what episode this is from, that’d be great
