An Chilean-Danish artist named Marco Evaristti fried meatballs in fat liposucked from his body and served it to his friends.
Evaristti produced 48 meatballs from his own fat, some of which will be canned and sold for US$4,000 ($6,200) for 10. Two cans have already been sold to collectors for US$23,200 each.Almost as wonderful as Piero Manzoni's canned shit from 1961. (But my favorite Manzoni work is "Base Holding Up The World.")

He claimed that the meatballs were not only delicious, but contained less fat than supermarket meatballs.
