I want to say I saw this back around the mid 2000’s.

It was an animated Halloween special told in 3 parts. The first part was about a dead cat that came to haunt the protagonist as a ghost.  The second part was about a group of kids trick-or-treating. The final part was about a bully teaching the main characters to “undress” women with their mind’s eye.

It was a very raunchy and profane cartoon.  I think I saw it on HBO and the first name of the producer/director/writer was Luke.

Thank you for your help!
