Sodomize her with a piece of splintered balsa wood.
Cut off her nipples with a rusty butter knife.
Amputate her hands & feet, then reattach them so she walks on her hands.
Nail her hands to 2x4's and then use a drill to knock all her teeth out. Afterward, cut out her tongue, simmer it in a red wine sauce for a few hours and enjoy the view of her lifeless body on the floor as you eat her tongue.
Just a few ideas, I have more if you'd like.
Dude you got some fucking issues man. Do you keep your mothers mummified corpse up in the attic? And dance in her panties to I'm A Little Teapot?
