Crappiest jobs.

Cleaning dead bodies. (Hey! I never did it.... One of my friend does).

My worst was (try to explain it in English). I had to sell subscription for a crappy compagny which sell books. When you subscribe you had to buy a book every month. If you don't choose one, they'll send you one anyway. I had to knock at doors to ask people to subscribe.
I did it 1 day !!! LOL
