Lightbulb Joke
Q: How many vegans does it take to change a lightbulb ?
A: Two. One to change it and one to get out a copy of The Ethical Consumer (or similar) and discover to his/her horror that the manufacturer (Thorn Lighting) is part of Thorn EMI who are involved in, errrr, I dunno, testing software on mainframes or making farms for 3rd world potaters or something.
