President Woodrow Wilson had a herd of sheep during his White House years. One, an old ram named Old Ike, liked to chew tobacco. During World War I, President Wilson allowed the sheep to graze on the White House lawn. This was part of the family's war effort; with sheep keeping the grass trimmed, no manpower was needed for that job. When they were shorn, the sheep's wool was auctioned to raise money for the Red Cross.
