Tribal Odessey

In some part of Sudan, marriage is an exchange of a bride with cows, up to a hundred of them.
The decision of who will be the husband is not up to the girl, but it is the big family decision. This is based of the number of cows he has.

Cow's urine is used to wash human hair, it makes their curly hair orange, considered as nice decoration.
To get the milk from the cows they stimulate its genitals by sucking it, similar to what we know as blow job. Except this is done to cows.

Interesting movie from National Geographic Channel.
