A program that is a palindrome (if you reverse its source code, you get the same program) and is a quine (if you run it, it prints out its own source code). Verify like this:
ruby palindrome_quine.rb | tee output
diff palindrome_quine.rb output # the output is the same as the source program
ruby -e 'puts $stdin.read.reverse' < palindrome_quine.rb > reversed
diff palindrome_quine.rb reversed # the reversed program is the same as the source program
