Family Guy is a fictional show, you need to provide a case in real life for it to be valid. Saying that this should be held as fact is like saying that someone can buy a space shuttle and fly it into space from their front yard and come back to earth with no problems (remember that episode? )
I know its a fictional show <,< XD the point i was trying to make is if it happened to you what would you do? keep the money or notify someone of it? according to a vast majority of people they would of kept it, and than in the end they would find out and send you to jail. Than everyone would starty crying saying something probably like " O I didnt know this was illegal its not my fault im getting this much, you should find the person that made the mistake and sentence him to jail and i should get to keep the money as the governments punishment for making the mistake."

and FYI ppl should be able to buy a spaceshuttle and take off into space on there own, it would be freakin sweet, plus you get to rub one out for a couple days and in the end you get to feel what its like to live in a snow globe. And in the end isnt that every um.............. messed up mans dream? ^.^
