we rewatched the funeral episode again the other night, maybe my favorite of season 2. We noticed the song that Ted is playing as he's getting dressed. He made a reference too it in an earlier episode. Also, pay close attention to the picture on his dresser as he's getting dressed, it's a big part of the finale.

Dear Lord I will never understand the amusement people get from “Rick rolling”
But I remembered the song because “easy lover” is a fantastic song and I love being reminded of it.
