I found this on the net. I remember some of these.
The exact nature of Barney's next job is unknown, but Fred inadvertenly gets him fired from it in "No Help Wanted," the 6th episode produced. (Fred explains that he told Barney to "put his broom down"; Barney later remarks that "it wasn't much of a job"). Fred then helps Barney secure a job as a furniture repossessor, but this career is never mentioned again and appears to have been brief. Other temporary positions include travel agent, co-owner (with Fred) of "The Drive-In," and (again, with Fred) private investigator.
You ARE the Man.
If I ever have another question, I don't care what the subject, I will call on you. To be honest, I have been asking my friends this question for 10 years and no one has had the answer. I don't know if you are right, but you sure sound convincing.
