What is the most absurd claim you believe?

Bryan Caplan says my most absurd view is philosophic pragmatism.  I say Robin Hanson’s most absurd view is to overestimate the chance we all become uploads in the next century.  I am not sure Alex has a most absurd view, except perhaps his notion of what my most absurd view is (hint: "one in twenty").

What is your most absurd view?  Comments are open.  Yes your comment should be crazy but serious too.  It should refer to a view which you actually hold, but many other smart people consider untenable and bizarre.
