So I kept it

Last Friday night I was home alone from about 930 till midnight
at midnight S come home an we have the following conversation:
S: do you know there is a leg behind your car?
Me: . . . . . . . What?
S: there is a leg behind your back tire
M: what do you mean a leg?
S: a leg, like a limb
M: are you sure it's not a branch?
S: no it's a leg

at this point S makes me get up and go outside to look at this so called leg. We get a flashlight and I put pants on and we go outside.
We walk to where my car is parked. And it is very dark.
Sure enough there is a leg behind my back tire . . . With a foot on it.
At this point I freak out and want to go back in the house, because if I was a psycho trying to lure to girls out of there house I would put a leg behind their car and wait for them to come investigate, at which point I would knock them inconcious and put them
in the back of my rapist van.
S, being the brave one, determines it is in fact a plastic leg. Not that that makes me feel any better, maybe the rapist was fresh out of real legs.
I demand we go back in the house and leave the leg where it is hoping that it will be gone in the morning and we can forget about this whole creepy situation.
But in the morning it is still there.
The leg is now residing on our front deck.
I'm hoping some one will try to steal it back and I will catch whoever it is.

The part that I can't figure out is : was this little joke aimed at me specifically or did they just find a random car to put it behind?

Either way, so creepy
