The worst job I ever had was working as a cleaner at a nuclear power plant in France. I had to go around collecting rubbish. I didn't have to wear special clothes or anything. There was no risk of contamination -- I hope.

I could name two. One was playing a snowman for a bank in Iceland. It could be dangerous because the kids would attack me in the malls and pull my nose. Also I used to clean a movie theater when I was 17, and I had to do the toilets.

Working on cars. I had to change the oil, and when I was underneath the car and taking off the nut to change the oil, the oil fell on my face. I always had oil on my face and on my hands and I was paid cheap so I quit after three months.
