Belly Buttons part two

As the most athletic of all America Presidents, Theodore Roosevelt had the most muscular belly button of all the Presidents of the United States. A sickly and asthmatic child, the young Theodore Roosevelt was a fanatical devotee of exercise to the point that he devoted part of his workout to strengthening the muscles of his belly button. He had an “outie” in which he did curls with a pencil fitted with two tiny weights. His belly button was in fact so strong that he once tied off his lariat on his erect belly button while roping a calf in a rodeo when his saddle horn broke in mid contest. It was quite an impressive feat.
