so, google showed me this....maybe the blogger meant the legend of Teddy taking on Bigfoot....

This shirt has the most believable fictitious image you will ever see. "Teddy Roosevelt VS Bigfoot"...I can see it. C'mon, the man would take on former pro boxers while he was in the White House. One encounter left him nearly blind in one eye! He scaled The Matterhorn, a 15,000 ft. Swiss Alp. After his presidency the 58 yr. old lobbied to lead an infantry unit in WWI!! He regularly skinny dipped in the Potomac River. Oh ya...He was shot by an attempted assassin and still gave an hour long speech with the bullet lodged in his chest. Bigfoot wouldn't stand a chance.
