Best/Worst bad movie theme music?

[Joe the Destroyer]

I was thinking about this song today:

...and I couldn't stop laughing.  It's so.......80s.  Not that that's a bad thing, but tap-dancing crap I feel like I'm going to puke hot pink when I hear this song (but not as badly as the one below).

It also got me thinking of starting a topic here, a place to sample and remind us of all the good/bad/awesomely bad/quirky/original bad movie themes. 

You know like this:

That music is one of my favorite things about Friday the 13th part 3   

Here's an old favorite - really swingin' and groovy man

Weasels Rip My Flesh (1979) and Bigfoot Night of the Demon (1980) both have the same bad music.

I love this theme music. I own a copy of it and will put it on at a party every now and again to see the reactions and the reactions are always the same. It's either "Oh my god what is this? It's rubbish" or "Oh my god what is this? It's the best thing I have ever heard"
