kermit.methods(false) will give you kermit's singleton methods:

irb(main):019:0>  s = ""
=>  ""
irb(main):020:0>  def s.x; end
=>  nil
irb(main):021:0>  s.methods(false)
=>  ["x"]

Also, you can't remove these methods from Object because they're not
defined there.  You'd have to do:

   class << s
     remove_method(:x)
   end
