An interesting fact

This is a birthday card that I received. I think it is an ironic take on the spurious correlations that get noticed. My favourite is the one that says that the more ice creams that are sold, the more people drown. There is no causal link. The ice creams don't cause the drowning but are consumed on hot days when more people go wild swimming. On this card, there is clearly a causal link but it is trivial.
