Every Halloween, there's always that one house everyone is afraid of.
Just knock. Why isn't she knocking? Do you think she knows how to knock?
But if you want real chills...
It's completely frozen.
...just wait till Thanksgiving.
I can't feel my legs!
Those are my legs.
In 3D. Rated PG.
(Lyrics) (When it gets loud, I turn it up)
Shake it like a bad girl up in Harlem
If You Want Real Chills
Just Wait Till Thanksgiving
