I went out for a meal last night - nice, relaxed restaurant. Afterwards I went to the loo. I'm standing in there doing what you do, when the guy in a silver suit materialises in the cubicle and says "I am Charndorff 4 from the planet Gorf and I come to warn you that if your people don't change their ways, you are all doomed".
Don't you hate it when they do that? Why can't they wait at least until you've washed your hands?
