Dress Yourself So You Look Scary
(to the tune of Deck the Halls)
 

Dress yourself so you look scary.
Fa la la la la, la la la la!
Be something weird or something hairy.
Fa la la la la, la la la la!
Don we now our ghostly sheets.
Fa la la, la la la, la la la!
Now it's time to eat our treats—
Fa la la la la, la la la aaaaaaaaugh!
