Jeff Goldblum got sick from selling pens.
The 'Jurassic Park' star has only had one job other than acting - where he spent a week working in stationery telesales - and hated it so much he is convinced it made him unwell.
He said: "I worked one week selling pens and pencils over the phone - that was the only other job I've done. It was horrible. My heart wasn't in it, and then I got sick, which probably wasn't unrelated."
The 57-year-old star rose to fame as a movie star in the 70s and 80s but in recent years he has been appearing in police drama show 'Law & Order: Criminal Intent', where he portrays Detective Zach Nichols.
Despite his film background, Jeff doesn't mind now pursuing a TV career and is pleased with his achievements.
He explained: "To be honest, my days are not spent going 'Why didn't I get it? I want that part.' There are people who go, 'I have $700 million, but so-and-so has $900 million. Why have you done this to me God, why am I so miserably second rate?' "
