You say this when someone tells a story so boring it could put a dead man to sleep and you want to mock them for it.

My uncle told the worst story about his cat and I said, 'A good story? Bro, that was a good nap.'

My friend told me about his day at work and I just said, 'A good story? You could’ve told me about your cat’s cat.'

At the party, I said 'A good story?' when the guy told me about his gym membership.
