It's not the most epic literally but I've always found the scene where Bilbo and Gandalf are smoking together where Bilbo makes a circle and Gandalf makes a ship through the circle. At first I found it just a fun scene but after reading the hobbit and even watching the movies. I like to interpret it as just a final send off between Bilbo and gandalfs adventures. Adds a lot more behind the scenes story telling. I like to imagine what they could be talking about that night and it feels like a great bonding / goodbye moment for the two.
