#1 If I like it, it's mine! Else, you may keep it (perhaps).
#2 If it's in my mouth, it's (naturally) mine!
#3 If I can take it from you, it's mine!
#4 If I had it awhile ago, it's still mine!
#5 If I see it first, it's mine!
#6 If it used to be yours: get over it.
#7 If it looks like mine, it's mine!
#8 If it's edible, it's allways mine!
#9 If I chew something up, all the pieces are mine!
#10 If I hid it behind something, leave it there. I'll just hide it again ('cause it's mine!).
