The whole scene with his friend in the house makes ZERO sense
So I watched it again tonight in the first time since 2007 and it the scene makes so little sense!
So his friend is freaked out that he left his phone in the car of someone he suspects is a serial killer....he goes into the garage and finds a bag with a carcass in it (he assumes it would be human) and then he runs through the house screaming and knocking crap over and plays a practical joke on his friend.
Like seriously, in what universe does that seem like a remotely realistic action in this circumstance?
