While looking for references to an old song I wanted to hear, I accidentally found this fanfic of--wait for it--Buckaroo Banzai.
It's a real Mary Sue of a tale, in which Peggy gets killed off immediately and the writer gets to comfort BB (I'm strongly guessing with more to come, or at least in the writer's head). Of course there are plenty of errors in the piece (I think Devine is my favorite), but I admit I was surprised to see cummerbund spelled correctly. Probably used spellcheck.
Gosh, I miss Godawful Fanfic!
