You need hands!

You need hands
To hold someone you care for
You need hands
To show that you're sincere
When you feel
nobody wants to know you
You need hands
to brush away your tear

When you stand next to these animals, you realise you are going to come off second best if it should come to an altercation.
The hand is a non-SI unit of measurement of length standardized to 4 inches (101.6 mm). It is now normally used only for the measurement of the height of horses in some English-speaking countries, including Australia, Canada, the United Kingdom and the United States. With origins in ancient Egypt, it was originally based on the breadth of a human hand. The adoption of the international inch in 1959 allowed for a standardized imperial form and a metric conversion.
Although measurements between whole hands are usually expressed in what appears to be decimal format, the subdivision of the hand is not decimal but is in base 4, so subdivisions after the radix point are in quarters of a hand, which are inches. Thus, 62 inches is fifteen and a half hands, or 15.2 hh (normally said as "fifteen-two", or occasionally in full as "fifteen hands two inches")
