Riddles that make you go CRAZY

Who has a neck but no head

Has to be broken before you use it

what has a teeth but cannot bite

what has an eye but cannot see

what has many keys but cannot break locks

what breaks on water but not in land

how does a dog cross a river without getting wet?

what is white when its dirty

who is your father's son?

what is allways infront of you but cannot be seen
