“I have seen it stated that no expert is quick enough to run over a dog; that a dog is always able to skip out of his way. I think that that may be true; but I think that the reason he couldn't run over the dog was because he was trying to. I did not try to run over any dog. But I ran over every dog that came along.”
"Taming the Bicycle" (1917)
