I think this is a specific case -- maybe you will want to do
something every third/fifth iteration....

How about deleting odd? and even? and having:

    def mod?(x)
      @count_ % x == 0
    end

    def mod(x)
      @count_ % x
    end

the latter so you can pick out the value you want.  Iterate round
the clock and fire off lunch at mod(24)==13, etc....

I'd suggest next and next! to overcome this.

Should there be an inspect that tells you about @count_ as well?
