ThinkGeek has sold, for many years, a T-shirt reading ‘Go away or I will replace you with a very small shell script’.

I've said a number of times to friends, but never got round to actually writing down anywhere, that I've always thought that shirt would be improved by a backprint reading:

#!/bin/bash
case $((RANDOM % 3)) in
  0) echo "What?" ;;
  1) echo "I don't understand." ;;
  2) echo "Where's the tea?" ;;
esac

It just occurred to me this morning to wonder if ThinkGeek might like to hear that idea themselves. I looked around their website, and found they have a web form for submitting T-shirt ideas – and will even pay you if they use yours. Aha!

… not aha. It turns out that the terms and conditions for that programme require you to certify that you're in the USA or Canada. Apparently nobody anywhere else is capable of having worthwhile ideas.
