Brains vs. Brawn(1912)

Among the suitors of a wealthy widow was a middle aged scientist, and while the woman was glad to regard him as a friend, she did not see how she could ever accept him as a husband. The widow was a great lover of athletics, and one day dragged the professor to witness a meet. As they were about to return, an effort was made to rob the widow, and only because of the bravery of one of the young athletes, was the crook captured and the pocketbook recovered. In a few days it dawned upon the professor that while he might be a big potato in the field of science, he was only a small lemon in the garden of love.
