Well, we can simplify that a bit.  How about:

#!/usr/bin/env ruby

h = {"john" => 41, "mary" => 31, "fred" => 10}
h.each_key do |person1|
	h.each_key do |person2|
		puts "#{person1} shakes hands with #{person2}.  " +
			 "Together they are #{h[person1] + h[person2]} years old."
	end
end

__END__

I'm not very clear on what you were aiming for with the if statement, 
but if you tell me, I can probably add that back a little slimmer too.

Hope that helps.
