A Missile
A missile is like a confused kid who knows exactly where it isn't, but has no idea where it is. It subtracts stuff in its head until it gets where it needs to be, even if that place is totally made up.
My missile hit the moon and came back with a coupon for free tacos.
This missile took a wrong turn and ended up in my mom's closet.
The missile got lost and started a fight with a pizza delivery guy.
