Sir Isaac Newton told us why, an apple falls down from the sky And from this fact it's very plain, all other objects do the same A brick, a bolt, a bar, a cup invariably fall down not up So if you handle tools up there let your watchword be "TAKE CARE" If at work you drop a spanner, it travels in a downward manner At work a fifth of accidents or more illustrate old Netwon's law But one thing he forgot to add the damage won't be half as bad If you are wearing proper clothes, especially on your head and toes. These hats and shoes are there to save the wearer from an early grave So best feet forward and take care about the kind of shoes you wear It's better to be sure than dead so get a hat and keep your head Don't think to go without is brave The effects of gravity can be grave
