For the parent who wants his child dead, but can't bring himself to pull the trigger: an indirect filicidal device - the deeply damaged skateboard ramp.
"You go have fun, Jesse. Daddy picked you up a skateboard ramp."
"It looks a little old, Daddy."
"Every little boy wants a skateboard ramp, Jesse. Daddy got you one. Go play."
"It's cracked and broken and has holes in it, Daddy."
"Tony Hawk could handle it Jesse. You do want to be like Tony Hawk, don't you?"
"Now take your skateboard and go play."
"Oookay. Where's my helmet?"
"Helmets are for girls, Jesse. You're not a girl, are you?"
"Oh, and be sure to give your brother a turn."
