exit and quit aren't objects, they're methods.  What you're doing is
invoking them.  You probably want:

irb(main):003:0> Object.method(:exit).methods
["to_s", "unbind", "[]", "to_proc", "clone", "inspect", "arity",
"call", "=3D=3D", "public_methods", "taint", "equal?", "=3D=3D=3D", "method=
",
"kind_of?", "display", "instance_eval", "to_a", "type", "private_methods",
"freeze", "id", "extend", "=3D~", "eql?", "singleton_methods",
"tainted?", "is_a?", "methods", "dup", "nil?", "class", "instance_of?",
"instance_variables", "send", "frozen?", "__id__", "__send__",
"untaint", "respond_to?", "hash", "protected_methods"]
irb(main):004:0>
