Me: "This is the third case of primary hyperparathyroidism I've diagnosed this month. It's really the season for it."
An endocrinologist, completely seriously: "It is *not* the season for hyperparathyroidism. *Summer* is the season for the diagnosis of hyperparathyroidism, because the extra sun produces more vitamin D which makes the calcium go higher."
