This pretty much sums up Mac. (Tanks Alot Hawkeye's Super Mac)
If I like it, It's mine.
If it's in my mouth it's mine.
If I can take it from you, it's mine.
If it's mine, it must never appear to be yours in any way.
If I am chewing something up, all the pices are mine.
If it just looks like it's mine, it's mine.
If I saw it first, it's mine.
If you are playing with something and you put it down it becomes mine.
If it's broken, it's yours.
