Once when I was in grad school, and tremendously broke I did. I didn't want to ask my folks for money (don't know why) so I sold some jewelry. Basically, the way most work is, you go in and they give you money for your items, and then you have a certain time frame to come buy back your own things or the pawn shop gets to sell them to other people.

Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in sideways, thoroughly used up, totally worn out, and loudly proclaiming ‘Wow - what a ride!’ — Peter Sage
