Check out String#replace

>         self.split.each { |word| word.capitalize! }.join(" ")
>     end

class String
    def capwords!
        replace split.collect { |word| word.capitalize }.join(" ")
    end
end

Mind that you loose information about original whitespaces, all of them are
replaced with a single space character.
