Cartoon explains the difference between causality and covariation

Espen sez, "I thought you would appreciate this cartoon that explains the difference between covariation and causality. In English, the caption is 'During a convivial gathering there is talk of the unhygienic aspect of using galoshes. One of those present chips in: "Yes, I've also noticed this. Every time I've woken up with my galoshes on, I've had a headache."'"
