Flat Butter Knife

What would you do…?
If you were watching the news and it said that there was a mental murder on the loose. You turned off the tv to go to bed and you see him lurking through your house, electricity is off, you have no cellphone, and you have no windows. and the door is jammed and will not open and theres no way out. The way he got in was through the ventilation system. You are fat and can not fit through. Your only knives are Butter Knives, you have no matches/bats/animals/bodygaurds/boyfriends any one to save you. Now.. what do you do? [you have hide under your bed, its flat on the floor, you cant hide in the closet, you dont have one. you cant hide in the bathtub, you have no shower curtain to hide yourself.] WHAT DO YOU DOOOO!?!?
Kick him in the nuts then stomp his head
