At one pre-funding startup (in the days when 14400 was an excellent remote connection) we had a LAN set up in the basement of the founder with the largest house. Their daughter liked to "work" alongside us, so (partly to protect our unattended keyboards!) I bought a colouring-book program for her to use.

One evening, when her mother called down that it was her bedtime, she replied:

— Can't mom, busy working! click click click

— What are you working on?

— click I have to turn it all orange! click

Upon hearing that, we knew she was one of us.
