Playing Mafia Wars in Facebook is very addictive for a lot of people, including me. A few days ago me and my friends played together. We exchanged loots, collections, etc. And then we compare our earned achievements. There is one achievement called “Spreading it around” which can be earned by gifting loots, weapons, armors, vehicles, or even collections to your mafia friends. It must be done 501 times where every item counts as 1. So when I give 5 Grenades to my friend, it counts as 5.
