You left out "knocking over the card stack of the guy/gal you didn't like". My first program was a COBOL program, punched in, then fed to a 370/115. I was in my first semester of a Business Administration degree, fell in love with coding, transferred to a 2 year state tech, got an AS in coding and never looked back. Fortunately for me I never actually had to work on a Mainframe, PC's & 'Mini' computers were just coming into vogue, so that's what I've always worked on. C first, x86 asm, then C++.
