Reminds me of my first programming experience as a 10 year old kid. My dad showed me the QBASIC IDE. He typed one line of code:

    PRINT "Ach leck mich doch am Buerzel"

And hit Run → Start...

I broke out in laughter, realizing I can make real grey-on-black DOS programs just like that. It blew my mind and started my programming career.
