Harris,
Being the Phish elitist as I am, I need people around me to like Phish. That and the fact that everyone thinks you're an idiot for liking Phish until they find themselves liking Phish. In my seasoned travels of forcing my favorite music on people, I have found the way to show somebody Phish is to start with their studio albums (believe it or not) because of how accessible they are compared to jams. Get them hooked on that shit and then slowly bring in some of the famous jams (ie Mike's Song from the NYE 1995 show, for example). I feel that showing them only parts of the jams really makes it hard for the newbs to swallow as a tune, which they need to do in order to become a phan. Another smart thing to do might be to show them longer compositions without jams (like Fluffhead, Foam, It's Ice) because it's impossible to not be impressed by them. At any rate, I do not believe showing them pieces of songs is the way to go.
Word brehhhh, Bobby
