In a fit of boredom, I looked up punchcards on WikiPedia (http://en.wikipedia.org/wiki/Punched_card).

80 bytes per card and 143 card per inch. That is 11,440 bytes per inch, or 11.2 kilobytes. So, a megabyte is 91.6 inches, or 7 feet 7 inches. A gigabyte is 7,821 feet, or 1.48 miles.

This means that an average song, in MP3 format, at two and a half minutes long, is 1.2 megabytes or about nine feet, while an episode of Galactic Watercooler is at least 360 feet.

An episode of Doctor Who is 1.5 gigs, or two and a quarter miles.
