Musen

A musen is when the writer casually forgets how to spell, and the artist-turned-proofreeder fails miserably at his job.

"I've come to reclaim the emporer's pendant!"
"You can't have it."
"I'll have it off your corpse!"
"No. Listen, it's not here."
"Where have you hidden it?"
"In a MUSEN where it belongs."
