Only geeks my age will get this.
For the rest of you:
I remember when we had nuthin' but cards to program computers with. No fancified flat-screened T.V.-like contraptions like the youngun's use today. Softies. We typed them out at keyboards on huge desks made for the purpose. ALL DAY! and them we went to the computer room where they were read in an' ifn' you dropped the cards you had to sort them again, by hand. and the hallway to the computer room was five flights up, both ways!
