I always thought in the Weird Al song, "The Night Santa Went Crazy" the line that went, "And he slashed up poor Dasher just like Freddy Krueger!" went "And he dressed up poor Dasher just like Freddy Krueger!"
I always wondered who Freddy Krueger was, and why being dressed why him was such a bad thing.
