According to Wiki,
"The term may date back to American baseball slang of the 1880s, possibly from the pitcher Charlie "Old Hoss" Radbourn who is said to have suffered from cramps. Another story mentions a horse named Charley that used to work at Comiskey Park, the Chicago White Sox's ballpark. In those days, an old, retired horse was often called "Charlie"."
That just goes to show how utterly ridiculous some of our slang is, eh?
