My uni kind of had that course! They just didn't tell us what it was going to be ahead of time and it was horrendous. We all absolutely hated the professor but it was required to graduate so we all came up with various coping strategies and at the very end he said "congratulations this is what the real world is like!"

(I didn't believe him at the time, but in some ways he really didn't go far enough...)
