I found the following:

But the fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, they laughed at the Wright brothers. But they also laughed at Bozo the Clown.

---Carl Sagan

On this quotation page.

I hope I am being laughed at for the genius reason--though Bozo the Clown is probably as well remembered as Fulton.
