It's a Terrible Life (S04E17)

What would happen if the Winchesters weren't hunters? In this alternate life, Dean and Sam are living very normal and separate lives. Dean is a corporate man who enjoys health drinks and listens to news radio (not rock stations). He works at a company called Sandover Bridge & Iron Company alongside Sam who is in tech support. It seems as if the two do not know each other. However, after coworkers start committing suicide at an alarming rate, the two find themselves working side by side to solve the murders. (Warner Bros.
