+### Remarks
+
+Just run it with no argument:
+
+    ruby entry.rb
+
+I confirmed the following implementations/platforms:
+
+* ruby 2.0.0p0 (2013-02-24 revision 39474) [x86\_64-darwin12.2.1]
+
+### Description
+
+It prints JUST ANOTHER RUBY HACKER¡£
+
+### Internals
+
+This script uses characters in constants in Object class. It
+intentionally raises some exceptions. The second 'U' comes from
+RUBY\_COPYRIGHT, "Yukihiro Matsumoto".
+
+### Limitation
+
+This program does not work on JRuby because "return" does not raise an exception.
