Every year, Portsmouth, New Hampshire, throws one hell of a "thrilling" Halloween parade.

In a tribute to Michael Jackson's "Thriller," Portsmouth residents dance for the king of pop every Halloween. The annual tradition began shortly after Jackson died in 2009. The dance also serves as a fundraiser for the local food pantry.

Anyone ages 9 or older can participate, but it requires six weeks of practice to get the zombie moves down...and the killer thriller inside.
