In one, Blaine asks the Warblers to forfeit Sectionals so that ND won't be disbanded.
Another is a sex one, of Blaine lying to Kurt and saying all Warblers were initiated by an anonymous tryst in a pitch-black room.
A third one I can't track down is one where Wes and David start calling Kurt and Blaine "the Kurt-and-Blaine."
Sorry I can't be more specific with that last one.
This is my first post here, I hope I have the right tags.
