Serial Killer?

I can't be a serial killer
As I have weak wrists

I push buttons all day in an office
Making cups of tea by the dozen

And at night I watch just comedies on T.V
My favourite being Glee
I have no friends, they all keep disappearing on me

So honestly I have no free time to kill anyone
I'm also too tiny you'll see

All though...........
My mother is buried under the patio
My father is stuffed in the freezer, nice and cozy with grandma
My brother is just getting cold
Soon I'll be having him for tea.............. yummy :)
