And they were.
I forgot to give a plot summary of Buttcrack. Basically, some guy's lame ass roommate shows his buttcrack way too much and is gettin' in the way of his relationship wid dis ho. Buttcrack man takes a shower with the radio blaring, and his roommate 'accidentally' tosses the radio in the bathtub, killing him. Buttcrack man's sister casts some sort of voodoo bull**** on his grave, and buttcrack man comes back to life, seeking revenge on his roommate for killing him. And also, his asscrack has the power to zombify people.
I wish I were making this up.
Imagine that, but about 3x longer.
