Who said give it a whirl?

The expression "give it a whirl" means to try something or give something a chance. It is often used in a context where someone is hesitant or unsure about doing something, but is encouraged to try it anyway. The phrase is thought to have originated in the 19th century, and is believed to have come from the world of horse racing, where jockeys would "give their horse a whirl" to see how fast it could run. Over time, the phrase has come to be used in a more general sense, to refer to trying anything new or different.
