You can sometimes hide the RPN but it takes work. I've got a HP 16C
calculator. It was always fun to leave it laying around. For extra
credits, set it to hex mode. If they got past the RPN, 45 73 + is WHAT?

Semi apropos, I saw a cartoon recently that asked 'How do you generate a
random string?" "Put a web designer in front of Vim and tell him to
save and exit."
