The other day I got a phone call from the vehicle rental office at BYU.  The guy on the phone sounded a little awkward as he explained the situation.  Apparently they were cleaning out vans rented by our department and found several foreign objects.  Among them were two bottles of pills, an unopened box, and a carton of fetal bovine serum.  As he said that last part, a man in the background started laughing.

You know you are not a scientist if you find forgotten fetal bovine serum funny.
